Aftermarket Electric Locks – How do they work?

[julian]

Hi all,

I bought a set of aftermartket electric locks to install in my daily driver, a 1972 Olds Cutlass S. How do these locks work, since there is no ground?

They have a green and blue wire. Am I to understand that in one direction, power/ground locks, and the reverse unlocks?

This is the set I bought, if it is any help: http://amzn.to/qxSBcD
Also, looking around the web it seems these are used with a 12V relay. How does a 12V relay work?

Sorry for the newbie questions, I just don’t understand a lot of the electrical stuff, even when looking at the diagrams for my car in the factory manual.

I have been having the same issue with links, the easiest way to get them to work is to type it out. If you preview your post you’ll need to retype it.

Anyway onto the question, I am not sure which one you bought but I would think the relay should be with it. If you want it to be a good looking install I would suggest tapping into the fuse box (if you have any empty spots). I would also think there would be a ground, Its kinda weird not to have a ground…. Anyway this link should help with the fuse box tapping.

If you can get a picture or a working link up, I’m sure others will be able to help more then I could.

Also you might wanna check youtube for videos of them being installed. I know its easier for me to learn by seeing it done then trying to read about how to do it.

Its crappy quailty but it might show you enough to understand what your up against

hi,
i installed a similar type locking/unlocking kit in my VH Holden Commodore (from australia)….
if you purchased a kit, it should have come with a box that has a lot of wires on a connector that jacks into it…there should be a red wire with a fuse holder on the end of it and a black wire, red being batt 12V+ and the black being ground….there should be 4 green wires and 4 blue wires…these should be allocated in pairs…one for each door (assuming it was a 4 door kit you got)…usually the kit would come with 3 solenoids that are two wire (green and blue) and a 5 wire solenoid that is destined for the driver`s door …it has the blue and green wires as well as 3 others which serve for the automatic locking and unlocking of the other doors of the car when the driver locks or unlocks his door….also on this box, on the connector there should be 3 other wires for connection to an alarm remote control (if your kit did not come with remotes) and to the hazard circuit of the car to flash the indicator lights when the car is locked/unlocked (this is advised to be connected with a diode, to prevent damage to the circuitry of the lock /unlock control box….)

as a word of advice, carefully observe the locking and locking mechanisms within each door of your car, what i encountered with my car,,,,when locking the doors with the solenoids, when the front doors locked, the back doors unlocked…and vice versa….this was a simple solution…on the solenoids of either the front doors or the back doors should be connected in the opposite colour code..based on the flashing of the indicators (if connected..one for locking the car and two for unlocking…if your kit is similar to what i installed)
i hope this was of some assistance
