Question: Getting an 88 steering wheel to fit a 91 Supra
 

Title says it all... I got it to fit, but the harness for the cruise is different. I need to know what prongs in the outlet are for what. I think that for the horn there is a wire that is grounded somewhere on the steering wheel that goes to the harness and the outlet has a prong for a wire the the horn itself. Is this correct? If so, I still need to know which prong is for what since I do not have a stock steering wheel to go by. The car came with an aftermarket wheel that did not have the horn or cruise control hooked up .. Here are some pics to illustrate my question...

Thanks in advance.

i dont do much wireing myself but i remember a old thread about putting a late model mk3 steering wheel on an 87 year and that you would have to addap the wireing to have all factory functions so i would assume that its the same vise versa

Trying to locate this thread you are talking about. Do you have a link ??
