Description

Fused main battery power harness for Holley HP, Dominator and Terminator X ECU’s. Built in-house by Jolt Systems in custom lengths.

Is the battery mounted in the very back of your truck bed or land yacht? Save the pain of extending such a critical power harness with butt splices. Or at the other extreme, is your battery mounted up front on the floor board in your race car? Save the waste of cutting a universal harness down, while getting a cleaner install too!

Compare to Holley part no. 558-308.

Features
