i have everything installed in my scrambler. now i just need to hook up wring harness/computer to cj wires. any help would be appreciated. correct me if im wrong, big orange is battery, little pink is key on, big red if fuel pump, green is speedo, white is tach?
Are those wires the CJ harness? I don’t recall seeing any weather tight relays on a stock CJ harness.
If you need a key hot in start/run you can use the power feed to the choke on the carb. Should be a thin red wire (circuit 52c). 16 ga wire.
Tach signal should be red with a tracer (circuit 13a or 13b; changes to circuit 13c at firewall connector; 13f on engine side; then to 13d at coil +) at the coil it should be white with a tracer. 18 ga wire.
Constant power is circuit 12c, but that wire has a fusible link integrated between to battery terminal and the starter relay terminal. 14 ga red wire.
BTW, beautiful part of Texas you have. My lease is in Llano and we frequent Fredericksburg when we can.
got it figured out with some help. orange is battery. pink is key on. red out of fuel pump relay is fuel pump.
the green from coonector is vss. white is tach.
this is original wiring harness on a 2000 5.3L truck engine.
