I've been searching for hours today on this and can't find the answer.

I just installed the LTCC on my 94 Vette, fired right up but no tach.
Bob said to connect the tach wire to the white LTCC wire. I Did and the
tach worked BUT it Throws a code and turns on my fans? I'm going to try to get a scan tonight and find what code.

I was just wondering if any of you have ran into a similar problem. There is only a few guys on the Corvette Forum that have installed the LTCC and it seems my problem may be specific to 94'.

Thanks!

Maybe it is something specific to the Vette. Cuz I hooked my white wire up and all was fine. Your best bet is to work this turn with Bob. He has more of the answers on something like that. Sorry, wish I could help

 

On my 93 Z28 there is a small black box in the harness near the stock coil that is a "Tach Filter" that is in-line with the stock tach feed (what you would have hooked the white LTCC wire to). I had to eliminate the the Tach Filter from the circuit to make it work. Hope this helps.

 

Thanks Guys!

What I had to do was hook into my PCM harness at A13 where Bob
Said there was a tach output. Did this last night and all is Well!!!

Thanks again!
