My car came stock with a non power pull down. It's a 91 so it uses the later style mounting and motor. I bought one off eBay, plugged it all up because most of the connectors were the same anyways and as soon as I hooked power to the motor my tonneau cover solenoids starter clicking like crazy. Obviously I know now the wiring is different but looking through my GM repair manual I can't figure out the differences and which wires I should switch around. Has anyone done this on a vert? Or might be able to take some pictures of the setup in either a hardtop or vert?

Or can anyone help me wire it up correctly? I could take some pictures too...

 

Here's the diagram for the hatch pulldown and release switch, sorry what I use doesn't have anything for the convertables but this should be the same.

 

I have solenoids I have never been able to use, and my power pull-down stopped for some dang reason... I put most recent pics up on the vert section, should be there in one of Lon's threads...or in a reply to him anyway, try a search to see
It is an 89 however

I just read your original post I didn't see that anyone mentioned that the tonneau cover and the trunk hatch motor have a relationship. Your trunk won't release when the hatch is not down. Although I worked on mine a few months back, I have forgotten exactly what connections are required to get the tonneau cover and hatch motor talking. You do need to know, however, that one will not work without the other in the proper position.

 

I haven't even looked at it since then.

My trunk is completely manual right now. So when I turn the key, no matter what, it opens.

Not sure what you are talking about, hatch not being down? I don't have one...

I think I'm just going to strip the connectors off and wiring it up fresh. Seperate wires for everything. Just need to figure out what all the pins do...

 

On covertibles, the trunk will not open unless it sees that the tonneau conver is locked into place. That is done so that they can't both be open at the same time. It is unique to the convertibles and there is a sensor that detects it. When you install your hatch pull-down motor, it will have to have that connection. I would imagine it can be overridden, but I don't have knowledge as to how. I am not sure if the hatch motor you are using is from a convertible or not.

Do you have a trunck release button on the console or dash? If so, when you don't have things connected correctly, you will get clicks from the tonneau release solonoids.

There were some posts in here 9 months or so ago that covered this topic pretty well. Let me know if you can't find them and I will try to look them up.

 

Necro'd!

No switches at all on the dash/console. This car wasn't optioned with pulldown from the factory. I've thought about delving back into this but I haven't looked at it since about when this thread was still active. Anyone shed light on what wires to pirate? If not I'll just jump in, in the next few weeks when school is out.

 

The only thing I see in diagrams is that neither the tonneau release, nor the hatch release will function is the e-brake isn't set (manual) or , the car in park (auto).

The (release) relay, for either, ground runs through the interior release switches and terminates through the ground in the brake/auto shifter. Both hatch and tonneau share this same ground.

The relays also share power from the ACC fuse.

That is the only common things the two share, looking at '92 diagrams (for camaro).

p.s. I'm not so sure to be happy about being quoted in your sig but, I'll admit to laughing a bit when I remembered the post it came from

 

Hrmm... Okay. Well the car was originally an auto. So I guess it's grounding itself through what's left from the selector switch? Odd. I didn't think I did anything there but yank the neutral safety wires (err, park safety wires) for the starter. Must be a grounding issue then. I'll have to just tear into the back a bit and just start tracing wires.

This is the first time, on any message board, in all my years of forum posting (15? maybe more?) that I have quoted someone in my sig. I seriously laughed so hard it hurt when I read that.

 

lol... well, as long as you enjoyed it... you weren't alone.

Here's the ground for the tonneau... the hatch release diagram looks nearly identical...
It is a continuation of the diagram Klortho posted, the tan/white wire from the hatch release...

*edit... oddly, looking at the auto, it works in neutral too. Leaving it able to be drivin down the highway, put it in neutral and release the top or hatch... good idea.

 

I dont know if will help you or not but I have a t top car with an electirc pull down motor.. When i rewired the car all I did was run 1 hot wire from a spare port on my fuse block to the blue wire in the pull down motor harness.. I grounded it with the black wire in the harness to the body with a bolt that holds the motor in place.. This motor works by interupting power or reversing polarities ( dont remember exactly the method but the colors are right. did it a long time ago now) with a switch that triggers when the trunk is latched. hoped that helps
