tach gauge

[tiggerz]

Wondering where the electrical connection is on the tach. Its not working and I have checked all fuses and connections besides going into the tach itself. Instead of taking the dash apart, I took the fuse panel off and have just enough room to stick my arm up and feel around the back of the tach. Cant find any connection.

As best I remember, the lead(s) run in a harness from the ECU..I suspect cracked soldered connections at the cluster...

Check my posts - '97 had the same problem - there are for pin connections from the tacho gauge to the printed circuit board. Martin (new Zealand)

Connection is through one large connector to the back of the cluster. There's no separate connector for the tach.

I'm talking about within the cluster - 4 Connections from the tacho to the printed circuit board - Read my posts on the subject. I'm certain tiggerz problem is like the one I had - Martin

According to the schematic that I have, the tachometer signal is on pin 6 (of the 56 pin connector); the green/red lead... Ron

How are you going to fix that without pulling the cluster?

I did take out the cluster and opened it up to expose the dry cracked solder joint - It is going ever since with no problems

If you repair your own cluster then you retain your mileage reading

Yeah, sorry, mixed up the two tracks in this thread. I thought it was the OP trying to do a repair through the fusebox "portal".

So I just drove to Denver (Im from colorado springs) and about half way there the tach and boost gauge both started working. Then when leaving they didnt work again. So Im guessing it is what you guys are talking about. Thats what Im going to get into this weekend. Ill post back to update on how it goes. Thanks for the info

If you give a good slap on to of the dash above the cluster you maybe able to get it to come on or off. When you take out the cluster which is bit of a pain - remember to disconnect the negative battery cable. Good luck - Martin
