The big red wire that goes to the alternator post gives you your volts.

Does that mean that the 95 alternator wire needs to be hooked up to a 12 volt source in order for the "alternator gauge" to work? The only wire that I will have going to the alternator would be the one coming from the battery, plus the connector that plugs in. Right??

The wires that are shown on page1, are they ground wires? Two I believe had eyelets broken off.

That looks like a ground wire.I dont know what kind of wiring harness you have but i have a stand alone harness.I have a plug for the 5.3 alternator from the wiring harness that controls alternator from 5.3 computer.i also have a red wire from harness that goes to the post of alternator and i connected my red wire that went from my trucks original alternator post and connected it to my 5.3 alternator post.The old alternator wire that plugged in to the original alternator i am no longer using.

Thanks, gagliano7. I've got a custom emmisions harness from S&P, hope they put it together right. Today hooked up my ground cable and ground wiring. Tomorrow or Sunday I'll put oil over the rockers, fill the oil filter and crank it over until I see that its getting oil pressure. Hope it works.

Need help. Hooked up the battery, all grounds, filled up oil filter, put in about 4 quarts oil. Hooked up the oil pressure sensor. Cranked the engine a good 20 seconds for a couple of times. No oil pressure on the gauge. My spark plugs are all out, valve covers too. Do the spark plugs need to be in the engine when I'm checking for oil pressure? What do you think?
-
Check if you are getting oil up to the rocker arms. Cant imagine why the plugs would need to be in. Can you put a mechanical gauge on to check for pressure?
-
I'll see if I'm getting oil coming out at the rocker arms. Can I get a mechanical gauge at any parts store?
-
Which oil pressure gauge are you using?I had to hook up the wire for the fuel pump which goes to the original oil pressure gauge for mine to work.One wire to ground one to gauge and one to fuel pump.
-
Its the original oil pressure gauge from the truck. One thing, the adaptor that I'm using is from S&P, and I wrapped teflon tape around the threads of it as well as the sensor. Could that have something to do with it not grounding?
