Getting the TAC to work...

[harrisp7385]

I just did a sr20det engine and manual swap in my 1990 240. I was wondering what I needed to do to get the TAC to work? Suggestions or how'tos would be great. Thanks

you need a tach out of a cluster from a DOHC ka or a jdm (sr not ca) cluster

do u have to replace the whole gauge cluster? cuz mine is doing the same thing... no tac, and the fuel gauge is fubar too... but i think thats a different problm honestly lol

Your problem is probably the cluster itself. Usually you only need to replace the tach, not the whole cluster.

well the speedo works and the temp works too... the fuel gauge works but its off... like i fill the car and it reads half tank and when its empty im like negative gas haha

sound like the gauge has a bias error. If the needle got bumped when you had the cluster out, could cause it.

The sender could also be suspect, but when those go, the gauge gague just falls to E and stays there.
