Anybody Recognize These? (Electrical)

Howdy

I just finished up making a new drivers floor pan and firewall on my 76 150 and when I was tucking wires out of the way I came across these guys. They were free hanging about 3 inches away from where the park brake cable runs through the floor of the cab. To me the red connector/port looks alot like the EEC-IV self test output on my 88 Bronco. The little one looks like the ABS test port on the bronco too. No idea what these are to be honest hah so I figured Id ask. thanks

steve

I believe the orange plug is connector C419 which is for the seat belt warning and the gray plug is C420, also for the seat belt warning.

Yeah, I think the orange plug went to the alarm's buzzer under the dash and the gray connector went to the switch that was under the seat.

X2 on red one it seat belt buzzer elec connection, buzzer itself should be mounted up under dash on side inner wall. Where the cab thru rubber plugs are.
Sort of behind/beside the headlight switch.

The other connects to your dvrs side seat belt female part after a small wire run across the floor pan area.

Just so you know these trucks DO NOT have a EEC-IV self test ability. I bet some of us wish they did at times. lol

PO must have tucked them away. Thanks for the info.
I wasnt saying the truck had a computer test ability I just meant it looked like the one from a previous fuel injected vehicle I had.

Totally understand what you were saying about the plug, I just wanted it to be clear to anyone else that reads the thread.

Ahh I getcha my bad amigo. Took some time to follow wires after you guys told me what those connectors were. finally explained why there was a green wire under the carpet and insulation that ran from under the dash to the back of the cab haha. am I safe to leave these disconnected or is there going to be a small drain on my battery?
