thats because the oem plug was for a heater blower inside the tub typical for 76 and half of 77 CJ's and the new painless plug is for a heater system were the motor was outside in the engine compartment. typial of half the 77 and later CJ's

Call painless and see what they can do for you

Call Painless. They will send you any connectors you properly need. You have an early 1977 CJ7, which had a two-speed blower moter and it took the two-connector plug. Starting in late 1977, they went to a 3-speed blower motor that used the 3-connector plug you see for the resistor. Also, in late 1977, the 12 volts for the heater blower connected to the motor power terminal, which stuck through a hold in the firewall into the engine compartment and was connected to a heater power wire on the engine wiring harness.

does any one know if i can ditch the plugs and just wire it up directly? the plug from the motor has 2 wires and then there is a ground coming from the motor housing and the wire kit has 3 wires going into the plug. the wires are not the same color so how would i wire it up?

I am having the same problem with my '76. I called Painless, and they were Clueless. Did you get any resolve to this? I've seen the heater plug in the engine compartment, and wonder if there's something you have to do with it as well.

Well it depends on the switch you have installed. If you still have a 76-77 switch then you can just make up a new harness just for the Heater or use your old one over.

If you have your old switch and plugs, which it seems you do. Then connect the Tan wire from the new plug to the tan wire on the old plug. This supplies power to the switch. The other two wires, orange and red I think, go to the plug shown in the picture above.

Then get rid of the 3 wire plug and new heater switch plug.

If you want to use the new 3 speed switch and try running it with only two speeds, let me know.

In either case the simplest is to reuse your old connectors and switch. Snip the power wire off the new socket and connect it to your old switch socket.

Thanks John. I am actually updating everything in the dash and ordered the old '76 style two speed switch from 4WD:
2 speed switch: Heater Motor Switch by Omix and Other Jeep Parts and Jeep Accessories by 4 Wheel Drive Hardware

I may hold off on installing it in lieu of what you said and update it to a 3 speed just in case at some point in the future I may have to remove and replace the blower.
3 speed switch: Heater Motor Switch by Mopar and Other Jeep Parts and Jeep Accessories by 4 Wheel Drive Hardware

I'll repost once I figure it out. There is little to no info regarding this.
