86 alarm bypass

Having intermittent problems with my factory alarm. How can I bypass the alarm on a 1986?
Thanks

There is a flat 8 pin black connector behind the CE panel.

I think its the only flat one with 8 positions --- you may have to lean the panel forward to find it.

Unplug. Take the female half. Link the wires at terminals 4 (black/red) and 1 (yellow).

Wrap some electrical tape around each of the now-separate halves. Tuck them behind the panel.


Intermittency often comes from corrosion in the 2 door contact pins, the hatch contact pin buried below the lower hatch receiver, as well as corrosion within tiny contact switches installed at the base of each of the 3 alarm lock cylinders.

Thank you.
I have had an issue twice with the alarm not resetting while parked on an incline. Cranks with no start. If I move the car (push) several feet it will start right up. Is there also a sensor in the system that detects the degree of angle to prevent towing?
Thank you again

Interesting.

There might be a mercury switch in the hood, embeded in the light holder. Not sure.

Hood light should trigger with parking lights on, and hood open.

There is a push switch also, not sure its function, might be the electric fan safety switch.

Good question. Wally Plumley would know.
