Ok I think I might be loosing my mind or something. Below is a picture of the cluster connector from my 98 TA dash/cluster. In my research I found that its easier to swap in a 97 gauge cluster since the 98+ were all fed from the PCM. my problem is every pin out diagram ive read doesn't match up to the 98 cluster plug thats below. For instance theres suppose to be a white Tach wire at B13, My connector doesn't have anything at B13. the pink wire is in the wrong spot etc... I cant find a shop manual pin out for a 98, all I have to go on are these that Ive found on the web... anyone know whats up?







FYI, this is for a 98TA dash with a 97 cluster thats going into my 91 Z28....

 

good luck!

 

You're right. The 97 will be easier to install. Problem is you have a 98 harness. Your pinout above says the 97+ are all the same. They aren't. the 98 is a single year set-up and 99 up are the same. Since you are basically building it from scratch, just start from the cluster and wire backwards from there.

The other option would be to get a Helms manual for the 98 and 91 plus a pinout for the 97 cluster. Together these would give you the info you need to pull it off.

By the way. You need to ground C1 to keep the ASR light off.

Thanks for the info!! I repinned the 98 harness just like the diagram "97+" showed, some of the wires didnt match up color wise but that doesnt matter... frustration set in and I had to put it down and go work on something else. Im hoping I can get back to it tonight, from what I can tell it looks like its just either a ground missing or a +12v wire crossed.. thats thte only thing that would make the dash do the weird things its doing(ie dash lights no working all the time, fuel gauge not working when head lights are on, direction lights dimmly on when head lights are on and high beam indication not working when headlights are on)...
