Pro Wire Harness
Handcrafted LS1, LS3, LSX harness systems built in the USA — new TXL and GXL synthetic low-resistance color-coded wire, mechanically crimped and soldered to every terminal.
LS1, LS3 & LSX Wiring Systems and Tuning
At Speed Scene Wiring, we physically handcraft only the finest LS1, LS3, LSX harness systems that money can buy. Our custom wiring harnesses are built in the USA with new TXL and GXL synthetic low-resistance color-coded wire. A good mechanical crimp, with the correct tooling to all terminals, is our standard — then soldering all terminations. This undoubtedly seals the deal, and the end result is uncompromising quality, second to none.
