Hi! I am in the process of of a rather difficult swap and need help with wiring issues. Here is what I'm dealing with:

I have a 98 Civic EX (automatic) (my DD)
B18c1 Engine with original LS transmission (automatic) and stock ECU
Im keeping the civic AUTO! Why? Part of the challenge.

I have the old engine out and have resolved the mounting issues. Where Im running into trouble is the wiring. I don't think a conversion engine harness, (civic to b18 auto) exists. I need the ECU and TCU to function properly with this setup. Do you think it is possible to have a fitting harness fabricated? Also, if there are any other potential issues I may have with this swap, let me know.

This swap may seem pointless and stupid, but it is a goal of mine to complete it and to get the car running. Please help! id like to make some progress on this project Thanks!

Any help is appreciated!

 

Good luck. Pics of mounted auto transmission?

 

Anything can be swapped, I love engine swaps, but always wonder why so much effort in a swap like this, especially auto?

You can p/u a DA/DC (Integra) automatic, all ready to for $1000-$2000

 

You're more than likely going to have to get very friendly with the FSMs for both cars and get good at reading wiring diagrams to make your own harness. I've always understood that the biggest hurdle was the physical clearance with the Integra auto transmission but you say you have it figured out? Care to explain how you did it?
