GS Auto to Manual swap Vris issues?

Post by KaBa »

Ok, so my attempt to fix the auto transaxle in my '93 was a fail, so I'm swapping over to manual.
I've pulled all the relevant parts from a wrecker donor car and am preparing for a seamless swap...my question for those in the know is, how do I best deal with the Vris issues mentioned in the sticky? Is there a wiring trick or should I pull the whole engine harness from a manual car ?

Working on resolving it, its a result of the wiring being different...

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

Believe me, uber lurking has provided me with many hours to read up on the swap ( search doesn't parse the word swap btw) prior to asking this question.
I only ask, as I could not find an answer to the vris issue with atx harness/ecu with mtx. I have thoroughly researched the rest.

Agreed, though I am wanting a more elegant solution...i suppose i will pull the engine harness and ecu from a donor to get fully functional vris. I have a kl31 ecu waiting in the wings for an eventual kl motor upgrade for this car, so this is probably a better way to prepare for the future.

I have the engine bay harness for sale. It has been modified for the HEI/External coil module. Also no EGR plug, you won't need it since you're getting the KL31. But I am happy to sell it to you if you're interested

Thanks SuperK, however I spent my Labour Day at the local pickapart pulling a mtx harness and ecu as well as some zx2 rear control arm brackets for both of my cars in preparation for poly bushings. These cars are getting rarer and rarer...I appreciate the offer of assistance :D
