Does this vehicle have a separate coil?

Also go to the ignition switch. With a DMM

1 or 2 wires will be constant 12volt+.

1or 2 will be 12v+ on accessory.

1or 2 will be 12v+ on ignition.

1or 2 will be 12v+ on starter.

TEST and let us know.

Does the vehicle have power locks.

I'm assuming contacts to bring on the door and trunk lights.

See if with either the driver or passenger contacts they both control the dome light.

I think we can forget dioding etc on a vehicle of this age.

I might be getting old, but wasn't that car built on a GM chassis and running gear? If it was should follow GM wiring for doner car

I'm sure the original came out in either the late 60s or early 70s and was a Studebaker, whatever that was. I can remember the Edsel as a child but as I was 11 years old, I never got the hidden meaning in the grill!

My issue for now is with the power door locks.I think the switch that i have now is not the correct one and i think I may need to install 1 or more relays to control these with my new alarm.

This is the wiring diagram now. The switch installed is SPDT.3 terminal center off.The connector is 4 wire 2 at the top 2 in center.I have checked the door motors and they do work.Apply + to one wire and - to the other to lock.Reverse that and uunlock.

So the Questions are.What kind of switch do i need and to hook up the alarm do i need 1 or more relays?Also the alarm wire output is 12v -.

Thanks for the help.

The switch you have now will work with the following set up:-

Feed the switch centre contact (common) from ground, then 1st. output, join to alarm lock wire, then to relay 85. relay 86 and 87, feed from 15 amp fused 12v+ constant share this with other relay.

30 to lock side motor wire.

2nd. output from switch, join to alarm's unlock wire then to 85 on second relay.

86 and 87 as above.

30 to unlock side motor wire.

87a on both relays to ground.

OK, assuming the switch you have has a momentary action, it's quite correct wired thus (discard the above diagramme):-

Common from your switch to ground*

Relay 1)

Join lock output to one of the terminals of the switch then to 85.

86 and 87 constant 12v+, 15amp fused share both relays.

87a, both relays to ground*.

30 to lock side actuator (or solenoid both the same) motor wire.

Relay 2)

Join unlock output from your alarm to the other terminal of your switch, join both to 85.

30 to unlock side actuator motor wire.

86, 87 and87a as above.

*Run a voltage test from your battery + terminal to your selected ground point, if it's less than 12.1 volts, take all your grounds to the battery neg terminal.

I have not read all of the recent activity about your situation, but from what I am gathering from Howie's last post, you really need to get a Single pole Double Throw Momentary switch. It will have a center off position and flipping the switch one way will lock the doors and flipping it the other direction will unlock the doors.

Or you could use 2 separate switches, but they would need to be momentary as well. One switch for lock and the other for unlock. They must be momentary.

Thanks.That's what i thought,but since it was already installed iI thought i might be missing something.I am not sure if they worked that way as i never tried them.I'll look for a different switch.
