'92 C1500 5.3 and 5 speed (don't stone me)

http://www.ls1truck.com/forums/searc...searchid=42290 Here is some speedometer stuff. For temp sensor I used the Camaro 3 wire temp sensor and wired my gauge to that so I wouldn't need to have 2 temp sensors. One for pcm and one for gauge. This way #8 cylinder is easier to work on. http://www.ls1truck.com/forums/lsx-t...or-wiring.html If your looking for headers Schoenfield are the ones I used. The alternator I used the 5.3 pcm to control alternator and connected red wire from old alternator to new alternator and eliminated the control wire from truck. My alternator gauge works. I used the trucks original oil pressure gauge on 5.3 with a pipe adapter so it will thread in. My truck is a 5 speed and the clutch safety switch works like it used to. I connected the white tach wire from my distributor to the new pcm. You may need to do a program change to get tach to work correctly mine works perfect.

Thank you, sir. I appreciate the information. Very helpful. I've already bought the S&P adapters for oil pressure and to run the "extra" temp. sensor in the cylinder head, as you were stating. I also have the Scheonfeld headers sitting in the box! So, you left the clutch safety switch untouched and it still functions as it used to? That's great. Also, there is no need for the fuel pump wire from the 5.3 PCM, correct? The speedometer link you posted above doesn't work, so what did you do for yours and the VSS?

Do an advance search in this forum and search speedometer titles. http://www.ls1truck.com/forums/lsx-t...eedometer.html My harness was already setup for stand alone and the fuel pump wire i connected to the new harness. I came off the fuel pump fuse under the hood. Just so you know the fuel pump power on the truck is connected to the oil pressure sendor. I left it that way so if i lose oil pressure my fuel pump will shut off and kill the engine. I think i fixed the link so give it a try. It just worked for me.
