Which wire goes were! – 4 Hours

Started the wiring process in earnest today, the Optima 51 battery was mounted in the Breeze front battery box and the negative cable was run directly to the engine block. A good location for this is a starter mounting bolt.

All quality automotive vehicles have the negative connected directly to the engine, a ground cable is then run to the chassis (see October 10th post – Headers and Exhaust).

The solenoid was then mounted to the driver’s side of the transmission tunnel, those who are reading this and have yet to mounted the engine will find this easier pre engine installation. This location was chosen as it is next to the battery cut off switch (also installed today) and next to the drivers foot box cable opening (the clutch neutral circuit will be used on this build and will be connected to the S terminal to engage the starter).

Two solenoids will be used on this build; the starter motor also includes a solenoid (as is found on many 90’s Mustangs).

A positive cable was run from the battery post to the battery cut off switch, a 10 gauge wire was run from the alternator to a Mega fuse and then to the same terminal of the battery cut off switch. A single cable will then be run from the other side of the battery cut off switch to the large solenoid post.

The Ron Francis stock harness assumes a 3G alternator so with a bit of wiring diet activity the 10 gage cable (labeled Alternator FD) was removed along with Alternator IGN (brown) cable and 3G alternator connectors.



Finally a number of other panels were removed for powder coating this week (radiator shroud, dash filler, fuse mounting plate, and one under door panel).
