Donated a door to the cause and looked at my buddies wiring job. 5.3 out of 02 suburban swapped into a square body short bed 4x4. Th350 and 205 case.
Looks stupid simple. He took the under hood electrical box, computer, harness and motor. He fed that big box with a hot, ground and the wire that went to the hei. He used the square harness to run dash Guages. Pretty clean and simple. I'm going to use the same method when I swap the 8.1 out of my 02 suburban into my 86 cab and chassis except I'm using the 4l80 against the 205 case so I have an overdrive. I'm going to use a pair of tbi saddle tanks and a suburban rear tank with ep381 pumps and 2 selector switches. Fuel ups should give me a heart attach
