I am cleaning up the engine bay for paint and all that, and need a little help on identifying what some of the wires are for, and if I need to keep them or can I tuck them. Keep in mind that I will be getting a complete rywire harness for a JDM h22 and will be keeping the internal dizzy that come with the H22.

First: I will be relocating the fuse box into the glove box, I need to know if any wires from the fuse box need to stay
Blue arrows-- these are for the Fans and the radiator sensor, need to stay
not sure about what the RED arrows(AC relay?) or the green arrow(no clue)
Image


Second: blue and yellow arrows, these plugs go into the vacumm box, but with the rywire harness, I am assuming that this will not be needed and that it can be tucked in the fender.
Green and black arrows: Can these be removed completely or do I need to keep them
Image


third: red arrow is for the AC canister, not sure about the greed arrow(Cruise control?), blue circle is for the headlight motor and relay and ground wires

thats the whole point of this tread, to figure out what I need and dont need so I can clean, prep, and paint, and by the way grease and grim gives a car character, and my ride is the ron jeremy 3rd gen ludes

Rev,
Pic #2, Green arrow is pointing to the Ignition Coil, Black arrow is pointing to the Igniter. (There also seems to be a ?ground? wire that ends at the Igniter plug mounting bolt.)

Keeping vs. tucking: I imagine they could be tucked--and should be important if the Rywire harness uses the stock ignition components for an H22A.

first pic red arrows are air conditioning compressor clutch relays. From the bumper they are just right of where the battery goes.

nope not on a '91. I am pretty sure its the same for all 3rd gen fuel injected atleast. Both fan relays are top right from fender side in underhood fuse box.

How many wires/terminals are there? If its four its your alternator green plug.
 
#12 ·
Well its a 8 bay connector I am pretty sure but the only thing I saw coming off the underhood fuse box with that connector number is the alternator voltage regulator. So yeah basicaly the 4 wires going to the green plug on the alternator. Its connector c238 in 91 etm pics and wiring diagrams.

I was gonna relocate the fuse box in to the cab, but how in the hell do you do it. can you even de-pin all the wires or do they have to be cut.

Tomorrow I will start the disasemble of the rack and pinion, until I am shit faced, hopefully my family will help me out :)
Heres a pic of the engine bay so far

You are going to be real happy with this when it is all done. Is that a fluorescent head light conversion?

You should squeegee that floor with SuperClean a few times. ;)

Yeah, I was just reading Guessman's thread where he used a 23 Pin connector and made himself a quick connect wiring harness as he relocated his fuse box into the trunk, I think I will do it this way but instead it will be in the glove box.

Use solder on the conductor to connector and crimp on the wire insulator for maximum connection and durability.

An extension is probably your best bet without creating a whole new harness.

I cut all the wires mine is currently in the glove box with the distrubution box.
It doesnt fit with the fuse box cover lid btw. anyways i only had to extend like 7 or so wires to make it reach the gloves box all the others u can pull through. I also notched the back of the glove box the wires get pretty bulky so having the notch there makes it easier

The quick disconnect thing is a great idea, if i ever re do the wiring thats def gonna happen.You can pretty much tuck all those wires iirc. Word of advice though, COMPLETELY tape up those relays if ur hiding them behind the fender a tiny bit of water will give u a bad day or should i say night.

I fried 2 of the headlamp motor relays before i figured it out. luckily i had spares.

You should definetly check out waytekwire.com I bought like 13 different colors of 16 guage wire in 100 foot spools each. Plus I think they are in your same state! So shipping would be extra fast. They have a lot of other stuff too like terminal connectors. Also check out http://delcity.net I think both have a $20 or $25 minimum. But not positive.

I think you have an 88- or 89 this is for an 89: you might find the multiple connector to plug and play a wiring harness extension. Hondapartsnow.com Somebody recently posted honda pin connectors too. Well just looked and no connectors for 89 and limited for 91.

Best bet would be to pic up extra connectors at the junkyard and create a patch with new terminals with stock old plugs the length you need to glovebox. I did this on my fan harness to install an rf remote switch and alarm siren to know when my fan kicked on when it wasn't suppose to and draining my battery. Just get both plugs and reverse them. May want to do some depinning to. If you were going to add fuses to your system I would buy one of gange boxes on delcity.net or search for best price blue sea brand name boat fuse box. I have both.

Just got a few more things to strip off the engine bay, and I will be hitting it with the simple green, with that being said I need a little info on how to do a proper paint job that will look good and last.
First off, I think I will just rattle can it, I could go and buy a cheap spray gun, but I dont feel like cleaning the fucker and I don't think my little 10 gallon air compressor will keep up, so I feel that a rattle can is the best thing to do.

For the most part the paint in the engine bay is pretty good, there is only a little rust where the battery was at, which I will grind down to the metal, other wise I will just sand the factory paint, which leads me to my next question: what would be the best rattle can primer that will work for my situation, From reading on google a 2k primer is what most use, but I dont know what kind of 2k primer is best for my situation, so any help on rattle can primers like brand or type of 2k would be repped by me :)

Also here's a good site with info on painting

Rattle can won't last as long. But you do what you got too. I would just treat the rusted areas with phosphoric acid and steel wool. Wear gloves. I think there might still be some available online. Other wise por15 makes some bare metal prep that is the new green stuff. Never tried it but my dad bought some but hasn't used it yet. I would then use a self etching priper on the bare metal areas and follow up with a duplicolor base coat can and clear coat. Color matcing ofcourse. I think you can get it at autobarn.com I think. The rest I would just go over with rubbing compound then maybe shoot clear over. I am not sure if duplicolor makes self etching primer for bare metal but they might. It will say if it is on the can. I know rustoleum does but forget what color it is. Want to say olive or tan like the dupont autobody primer used to be or still is. I think this is the best solution but it is up to you.

i got my buddy from fargo commin down today and is gonna give me training course on engine bay painting, he's been painting for 15 years, and may let me borrow is guns and compressor

Well Iam not sure yet on the color, but I have been leaning towards silver or charcoal, my H22 mounts and t-bar is a charcoal color, and the rear sub frame is gonna stay factory black, so I was thinking silver would be the best.

You not gonna really see the insert very much as they don't stand out like the mounts, if you are gonna go with a red VC I would also make the mounts read as well, you can also change your vac lines to red also. It depends on what you want or like,there are hundreds of engine bay pics on numerous threads, so look around and you may find something you like

Well whatever you decide I am sure it will look good. The acid I pmn'd you works realy good. I highly reccomend it for any rusted areas. One thing I see is IF your not going to remove all those pipes and fittings on the firewall for a more profressional result and to give a better paint sealed edge, Pop off those rubber grommets and tape up the pipes. Like the a/c, shifter, heater core, a/c drain hose. I think the ac drain hose can carefuly be pulled out. If not you might be able to reach it from inside at the bottom of the evaporator core box. Especialy with color change. Any time you remove them you will see the original color and painted rubber looks like crap and flakes and cracks. As far as your brake booster and master cylinder that is up to you if you want to paint it same color or mask it off.
