Re: **Question about transmission swap.**
I don't think you'll have to swap the ECU? the wiring harness I have no idea. But someone gave me this site before as kind of a "shopping list" <A HREF="http://www.geocities.com/bat_elof/tranny.html" TARGET=_blank>www.geocities.com/bat_elof/tranny.html</A> <BR>Hats off to whoever's site it is. Tell me how it goes Because I'm looking to do the swap next year, unless I come into some $ before then i.e. win the lotto.

Thats the how to and list for the RS, its not the same for the GS. Do a search man theres allota info on the swap. I'm planning on doing the 5 spd conversion too

This topic is covered better in the Automatic Transmission forum where they have topics dedicated to the swap

Re: **Question about transmission swap.**
I did this swap and i kept my ECU and removed the Auto computer. as far as the harness goes there is only 4 wires on the manual. I found my reverse light wire off the auto harness and cut all the other wires and taped them up. They are not powered since you remove your auto computer. It has been a few years since i did it and i have had no problems except when my car is in reverse with it turned off my reverse lights stay on. This can be fixed with a relay.
