Howell is one of the most experienced harness manufacturers on the market and covers just about any GM engine you might want to swap. Each harness is a custom made to your specifications - there are no off-the-shelf products. There are many options to consider - emissions controls, fan wiring, aftermarket gauge sender leads, extra harness length, or upgraded nylon braid sheathing just to name a few.
