Wiring guages

[tech1gmc]

I have a '87 Turbo T, I want to install some guages. Like tach, boost, water temp, and oil pressure. I need some help to wire the guages, if anyone can let me know, thank you.

 

["Turbo-T"]

Boost....just run a line off of the line before the EGR solenoid, make sure to get it before the check valve.

Tach....run the red to the IGN terminal off the fuse box, white to LPS, black to ground and green to the grey wire with a green plug dangling by the a/c compressor.

Water temp and oil...if you run electrical, use the same 12 volts switched on the fuse box you used for tach, then ground them both, then the oil psi sensor taps into by where the oil filter goes, the water sensor in the intake right side.
