Hey Jason Great video I have watched it about 12-15 times now. Lol I still have been able to get my square body running. It’s a 88 suburban Silverado. And in my hick head has only 2 large red wires. And a bunch of extra wires Anyways I still can seem to get mine running I have the aftermarket 4 wire fuse box Fuel pump comes on I get fuel to the rail but not pumping I was hoping u could help me please

Im really close to wiring my cucv for its ls swap. Good info i might message you if i have more questions.

You running the stock 2 pin neutral safety I take it ? considering your using purple wire to excited ? Or did you by pass the safety switch ?

And what did u did to the other wires? The ones u mentioned on the block, the grey/blue,a/c wires, yellow,etc????

Where did you get the aftermarket relay box?

So how do you wire it if it doesn’t have the third power wire

All of those relays and fuses for the injectors are not necessary. Injectors are fired one at a time. Not all 8 at once. I had a 15 amp fuse for bank one and another fuse for bank 2.

What harness wise do I need to keep from the squarebody.

I bought the holley terminator max x dbw im now poor this con version is not cheap

Since you're doing fuel injection. Why not have the computer control your fuel pump?
