And I have completed 90% of the Painless Wiring 14 circuit system for the Mustang. I am pleased with the kit. Very easy. I just wished it had more than 1 extra relay. I will use it for the electric windows. I will have to add 6 extra circuits for the high amp items like High Beams, Low Beams, Driving Lights, A/C Cooling Fan and Clutch, the Electric Radiator fan and the fuel pump.
Here is the UP taillight sequential wiring harness. I liked how it eliminated all the cutting and crimping. It connects to the PIAA back up lights (connectors already there). You only have four wires to hook up and a ground. You will have to put on your own connector to the rear harness. I just cut off a four wire connector from the old harness and spliced it on to the new one.
This is the dash wiring. Believe it or not it is almost finished. Only the radio wiring, one glove box wire needing to be capped, connecting the driving lights to a switch, and connecting one "Old Air" orange wire to a switched hot. What worked: the Painless kit fit very well. What didn't work: only one extra interior circuit, GM column wires had to be cut and spliced with the provided connector.
And if you are really counting, I have yet to install the wiring for the console. It will have the power window switches (Jegs $149), couple of gauges (probably boost and oil temp), and of course the nitrous switch.
I decided to hide the wiring as much as possible. I routed the wires out to the drivers fender,
Up under the wheel well, (the bolts are #8 x 1/2" self tapping screws and will be ground off, then hidden by the fenders)
