Hey guys,


I finally got around to installing my keyless ignition and alarm but I am having a bit of an issue with the door locks. The system I have will control negative systems, positive systems and type c +/- system.

I think from what the FSM says that the motor runs both forward and reverse. I have hooked up the lock and unlock wires and got the system to lock but it immediately blows the fuse on the lock or unlock wire depending on what button I push on the remote of the alarm. Can someone please describe how the power door lock switches activate the motor and or just tell me what wire to send a + or - pulse to lock/unlock the doors or do I need some sort of relay. I can post schematics from the alarm if needed.


The keyless ignition works great here are some pics of the install.


You gotta love the wires that you have to deal with.








I decided to install the start button just below the DIC I had to do a little cutting behind it but nothing major.

 

this is what I call a madness project ! impressive

 

Your Vette has Type C door locks.
Here is the door lock electrical from my 86 FSM.

Here is some info on the unit I installed, check out page 6 "Type C Locks", it might shed some light on wiring.

Here is their electrical page.

Post your schematics.

 

Thanks for the info agent. The alarm is similar but mine has...well...more wires here is a diagram of the wiring page. I talked to the guys at stardrive but I still get the same result it will lock or unlock the door but blows the fuse on the common (white or white/blk in diagram) after it triggers. I have wired all three ways the negative trigger will not blow a fuse but the other two will.

 

If you look on page 5 and 6, you will see that + and - triggered systems, the unit taps into the power door lock switch's wiring. Type C+/- had me cut the wire in switch circuit.

Looking at your schematic, I don't even see the door lock switch in diagram. I think this is the reason for fuse blowing, it's back feeding a ground from switch. Their info and tech help, seems lacking.

What make and model system are you using ?

 

Agent,

Its called Stardrive. Here is the link to the website.

I emailed the company and the owner Sven responded within an hour. He had me call him after hours to try and help me. He had knowledge but with my lack of understanding of my particular system I think I made it difficult for him. He doesn't seem have specific knowledge of early corvette systems. I think that it may be that I am tapping in on the drivers side when the passenger side is the master switch. Sven thought that the system must go through a computer circuit rather than relays. I got to thinking that it could have something to do with the arm/disarm of the factory anti-theft as well. From what I see if I go by my FSM the tan and black wires carry the pulses (12v+dc) when the switch is activated but if you supply 12+dc from the lock or unlock from the alarm it fires the motor and maybe pulls too much current in a completed circuit. The pulse from the alarm is brief, now that I think about it I haven't measured the output. Its blowing 10amp fuses but I should be able to see what it is doing on my voltmeter rather than a test light. I'll have to give that a try. Anyway Grey and Lt blue appear to be grounded at all times. And orange/black is hot at all times. But I don't see negative current ever in the Tan or black so what could be blowing the fuses? All right now I am just typing my thoughts so I will go out and do some measurements and post them up.

Now I remember why I hated installing alarms in my cars in the late 80's and early nineties.

 

If the schematic posted by Agent 86 is correct for your vehicle along with the
color code of the wires, you can wire the circuit like this.

Here's the schematic that was posted.

http://members.shaw.ca/agent86/Power%20Door%20Locks.pdf

Light Blue wire is for Door Unlock
Black wire is for Door Lock

In the schematic is a Light Blue wire going from the Left hand door lock switch
(Driver side)to the Right hand door lock switch (Passenger side). You cut the Light Blue wire.

Light Blue wire end going back to the Left hand switch connect White/Black wire.

Light Blue wire end going to the Right hand switch connect Orange/Black wire.

Cut the Black wire going from the Left Hand switch to the Right hand door lock switch.

Black wire end going to the Left hand switch connect White wire.

Black wire end going to the Right hand switch connect Orange wire.

Connect the Yellow and Yellow/Black wire to a fused 12 volts.

Make sure you cut the correct Light Blue and Black wire coming from the Driver side door switch.

You may find wires with the same color in the same bundle of wires.

It's called a 5 wire reversal rest at ground system.

 

Ah exactly what I needed, I will give that a try first thing in the morning. I had a feeling that I had to get tricky with the wiring from the alarm box to carry voltage through it. Thanks. I will post back the results but that looks correct to me.

 

 

Success !!!!!!


That was it. The system works perfectly now. Unlocks and arms when I approach and locks when I walk away. Now all I have to do is make a plug where the lock cylinder went and I'm done. Thanks to all who helped, couldn't have done it without this forum. Awesome group of people here.

 

If your system has that old thing where it locks your doors when you start the car....disable that POS right now......don't get lazy.

Old systems had this, the newer ones don't usually have that feature.

If I want the doors locked.....I'll lock them....
