Re: 5.3 into 87 tbi truck
I suggest looking in the Engine & Drivetrain forum under LSx swaps. Lots of good info there. Another excellent source is LS swapped Square Body on Facebook. Scotty has a lot of great reading pinned there.

Re: 5.3 into 87 tbi truck
Are you using a stock harness or a standalone harness?
I'm currently in the middle of an Lq4 4l80E swap into my 87 Formerly TBI Suburban. I'm done with my wiring and figured out where to hook into on the stock TBI wires. I'm using a standalone harness from LSX4U which has made the wiring easy. Tell me what wires your looking for on the TBI harness and I may be able to help. All of the wires I've tapped into we're at the bulkhead connector on the driver's side.
