Installation

These points are approximations, please refer to the closeups for exact locations:

The first 15" cable will run from the negative terminal of the battery to the chassis at the airbox bracket. Install it on the negative battery cable stud with the washer and nut provided, and use the nearest existing bolt at the inner fender. If you have removed this bracket and are using an aftermarket intake, use one of the bolts and a washer provided instead.

The second 24" cable will run from this harness bracket on the automatic transmission:

Or this bracket on a manual transmission:

And to the upper strut tower (with manual transmission):

And with automatic transmission (use bolt and washer provided):
