Hey guys,
I am almost finished with my wiring project on my ‘48 Desoto! I have used Wiring Harnesses unlimited and it is pretty good, especially if you do it in a short time! In my case it has been7 years and did the dash out of the car first then prostate cancer, heart stents after one heart attack, followed by several stents then had open heart surgery after two heart attacks 10 days apart! Recovery and spent time with my wife and started back to finish about a year ago! Have it wired except for backup light, all wires to trunk after dropping headliner! Taillights not totally complete! Got brown connected to right signal and green to left signal with black to each taillight, red to stop light, black not connected And can’t remember color to license light(if important will check). I decided to bypass the backup switch that was supposed to go to a bracket on tranny which was missing, so I go to a push button switch under the dash to left of steering wheel. Not sure what every switch is, but a lever switch near the push button switch is supposedly wired to control instrument lights! I can take pictures of headlight connectors and wiring which does work! I have a 6v Optima battery in a normal battery sized plastic container I bought to make it look normal! Have connected it, but it has a positive cable wired and connector to both posts! I ordered and received the correct size and color! Engine turns over with 800 Starting Amps!
I don’t know if this helps, but I will help any way I can!
