Ok well most of my guages aren't working, and the ones that are aren't working good.

I have a 1992 Camaro that came with the 305 TBI and 5 speed. Now it has a Speed Density 350 with a T56 6 speed. I also installed the Dakota Digital box using the instructions from our board in the Transmission and Drivetrain section. I'm using the 145mph speedo that came on the 350 V8 cars, so that shouldnt be the problem. I also tried a 110mph speedo in the car and same result.

Here is what I go
Speedo...sits at 20mph when I'm sitting in my garage.
Tach...nothing
Temp...kind of works but I think its showing low
Oil...kind of works, but this is defenitly showing very low
volts...this seems to be working, but who knows if its right
fuel...it shows low and I am pretty sure I am low so this might be right.

I used my 92 Camaro dash wiring and a 90 Pontiac engine harness. I don't know if that could be part of my problem or what? Any help would be appreciated to get my guages working again. This is really the last thing to do before its done.
