Oh ya engine temp doesn't show correct either. I've checked it with HPTuners and it reads correct. Not sure what's up, maybe a bad ground. I'll check that next.

My grounding and wiring problems come from the truck being stolen and stripped and the cutting of the OE harnesses.
I have used a Nelson harness and PCM tune. The tach wire that comes out of the pcm sends a different signal than my 1992 tach reads. Causing my tach to run about half RPM's. Thus, I needed to purchase a module from Bakerelectronix > http://mysite.verizon.net/vze7erz1/id1.html#tsdmod <. The module I purchased is the ATSD. Does it work,, don't know I have not put it in yet.
I have yet to tackle the Oil and Water. For the water temp I know I need to use the '92 OE sending unit and wire that in to the appropriate wires. I am going to install it into the plug that is on the rear of the right head (by the rear exhaust port).

The BakerElectonix tach module works great. I worked with him to get the the first one right and my tach read perfectly in my 92 with LS1.
