Yes, the fat wire wire in the 4 wire plug is the power feed for the coil.

That is the plug thats on the truck. The plug has 4 wires on it. A thick red one, red w/wht. White w/red, and red w/ yellow. Not sure what year the harness is off of. I started collecting these parts a while back, but it was a v8 with the blue grommet module.

Here are some photos of the 4 wire plug. You should have cut the wires on the other side of the plug at the junkyard. The red w /yellow is unused and is shown coiled and tied with a small black tie wrap.
The fat wire downstream of the black (3 in 1 out) splice is the source for the coil positive. The other two wires are for water/oil senders.

Somebody else had gotten to the harness before me and cut the plug off. Im going to try and use the plug that is on the truck and wire the new harness to that plug. Thanks again for the help. But i still have to find out if the white w/ red is for the oil or water and vise versa for the red w/ white.
