LS Engine Swaps Part 2: Sensors, Solenoids, and Harnesses

Recently, we posted several LS engine swap component parts lists for popular GM cars and trucks (and Fox-body Mustangs too). Created by Summit Racing’s tech experts, they take a lot of the guesswork out of selecting the correct components—motor mounts, transmission crossmembers, headers, and so forth—needed for a successful LS swap.

But that’s not all to getting that LS up and running. You’re going to need things like sensors, wiring harnesses, and solenoids to finish the installation. Summit Racing has you covered there, too.

These checklists twill help you keep track of what to get, down to the wiring pigtails for various sensors. At PowerNation and Summit Racing, it’s all about making your life easier.
