Wiring under dash

[outlawedcapri]

ok so i am converting my 86 capri to a 93 wiring harness computer and mass air and i ran into a problem the wiring harness is all pretty much the same except my 93 harness has a green plug with 6-8 wires and the 86 harness doesnt.


second i have about 3-4 wires that connect to the 86 wiring harness that run in where the computer goes then runs all the way across the dash to driver side into a clump of wires that split to the fuse box and chassis

any help in this would be great

has anyone put newer harness and ecu in 86 capri

well i just wanna say thanks after a couple hours of browsing the knowledge on these forums i found alot of useful info and have pretty much all the info i will need to do the swap. Gonna take a little break from it though as i am aggravated and that is not a good time for me to work on things

also i will be selling the complete AC/ Heating system so if anyone is interested let me know it was working about 2 weeks ago before i started stripping the wiring harness, motor, and dash

I found a Relay under the dash that is not plugged in and its bigger than most of my relays
e5zb-6c625-aa is the number on it i also cant find a plug to go with it anyone have any idea what it is

Where was it mounted? Can you post a pic?

This thread should have the complete '86 harness mapped out. You'll have to read the entire thread because I made some goofs which I corrected later in the thread.

86 EFI computer harness, power??

hmm i need to know what that Unknown underdash red - tan/gr - big yellow is? thats the only 3 wires i dont have connected on my new harness i have already spliced in the green one as the ford man says

[outlawedcapri]

My 3 Wire unknow dash connection goes over top of dash to the ecc harness the big yellow wire wire runs to the solenoid on the same post the + cable is on and one of the other wires dont remember which runs to the lil obd1 test connector and cant remember where the other wire goes

so i looked at this link and i was wondering if i hook my 93 harness green and brown connectors up the way this shows will that be safe? as in would that be right and not fry my Computer?
