    b18 swap into dx coupe

    okay thought i'd make a new thread because my old one is kinda getting off topic. but anyway my work on the project so far is here https://www.3geez.com/forum/showthread.php?t=71707

    update from that i started stripping my exi so i can pull the wire harness from that and the heater unit. so far i have fenders, bumper, rad, and dash removed. I've also ordered a gasket set, pistons, rings and bearings for the b18. I'll keep pics posted of the build.

    Re: b18 swap into dx coupe

    so today i started putting the wiring from the exi into the dx. anyway i was wondering if i have to change my back half of the wire harness. like where it unplugs by the drivers door? i compared the plug from the exi to the one on the dx and the one on the dx has 4 extra wires could someone tell me what these are for? one of them is yellow, one is green with a yellow stripe, one is yellow with a red stripe and the other one is blue with a red stripe.

    Re: b18 swap into dx coupe

    do you have a manual for these cars, either a haynes/helms/chilton? the wiring diagrams are in the rear, it's strange that the dx would have more wires than the ex-i, the dx is a four door right? could have to do with the door sensors, i dunno, but when i get home i can look in the book if no one else has chimed in.

    been busy so havent had time to figure out what them wires are for.
    but the gas tank on my parts car is in rough shape so looks like i need to find another one. I got an integra tank in decent shape maybe i can make that work?

    haha yeah thats gonna be awhile. still have to wire it for the b18.

    things i know i need to do:
    -add ecu plugs to covert to obd1
    -run wires for o2 sensor
    -change dizzy plug
    -add wires for the distributor

    but what i was thinking. i may sound crazy lol cuz idk if it will work like this but why couldnt i go to the j/y and rip the wiring from a teg that runs from the ecu out into the engine bay and drop it in the accord. sence most of the wires from the ecu go to the engine to me it seems like this would be easyer to do. then everything would plug right in for the most part.?

    Re: b18 swap into dx coupe

    Sorry its been along time since i've got to do any work on my swap. As of now i got the fuel line all in. Tonight i started test fitting the mounts in the car. I know where the bracket and passanger side mount goes and i know where the drivers side mount goes.
    But i got one mount left does this go in the front or the back? The integra engine and trans has a mount on the front but i can't see the swap mount going in the same spot but i looked on the back of the engine and cant seem to see where the mount goes ether? any help on where this mount goes.
