I'm in the process of converting my 4cyl 89 coupe to 8cyl. So far I have changed the front suspension, engine and tremec trans. Now I'm trying to wire everything back up. I think I have everything connected exept for the wires that go to the trans and there is a set of 6 wires and connector coming from the computer harness that the 4cyl dash harness doesnt have a mate for. Here is a pic of it. Could someone tell me what it is used for? Any help will be greatly appreciated.
4cyl to 5.0 swap?
- Thread starter 89bluegt
- Start date
An 87 5.0 harness was used.
Here is a pic of the 4cyl harness from firewall to computer. Everything is the same except for the missing connector.
And a few other progress pics. I still have to put the fuel lines on.
The rear is a little high. Its because I haven't changed the rear stuff over yet.

My 91 Notch is a 4cyl to 8cyl swap. I used all 92 GT stuff.....If I remember correctly, I think I had that same connector left free also. I was pist when I was putting it together, and I couldn't figure out what it was for. If I had that I left it hang free.
Is that on the passenger side kick panel?? IF it is I had that too.

ok well i know my car is a 93 but my 88 had a plug like that im not to sure about it but is it the for the fuel pump
It is easy. I had both cars stripped, and one car done and running in three days..by myself. I had no help pulling, swapping or installing my motor/trans/wiring/clutch pedal box. I went from auto to stick, and swapping the clutch pedal box took the longest. I had a hoist and air tools, which helped me out.
GET A DONOR CAR!!!! That will make things fast and easy. Try to find two cars the same year or 1 year apart. I had a 91 Cyl Coupe and a 92 GT v-8. Easy swap, everything was the same!!!

Congrats on everyone who did this swap. I did a t5 swap and put in a different 5.0 engine also. For me the most time consuming was the pedals also. Was way easier when I just took out the drivers seat and removed the dash. Then it was fairly easy. I decided to go with carbed though. The person who had the car before me hacked up the harness so bad which is part of why I just got a universal wiring harness and totally rewired the whole car. Was a fun project though and I learned a lot. EFI is great when it's all there and complete but boy is it a nightmare if it's not lol.
Sometimes pulling the dash makes it easier, I didn't do that on this car. But I did have the driver seat out. Boy those seat studs that stick up out the floor sure are hell on your back!!! I was all cut up, but my adreniline was pumping and it was 90* that day, and I wanted it done!!!
