Relay for trunk popper not working

I installed an Autopage RF405A keyless entry on my '96 Mystique, and now I want to add a remote trunk popper. I grabbed a solenoid off of eBay, and started getting the wiring done. I played with the multimeter a bit, and found that the auxiliary lead wire produced about a .4V burst (at least that's what the multimeter read) when activated. So I wired that to terminal 85 of the relay, and put 86 to a known good ground. Then terminal 30 went to a constant +12V, and I went to test it, but it didn't work. Wiring the multimeter from the remote unit output to ground still produced a voltage difference, but connecting the multimeter from terminal 87 to ground produced nothing. I know the relay is good, because before I unhooked it I used it for the horn honk, which I don't actually need a relay for. I also hooked 85 and 87 directly to +12V and 86 directly to ground, and I got a +12V off of 30, so I'm sure it works. What should I do?

You're sure about that? I was pretty sure that the trunk lead was negative until I tested it with the multimeter and got a positive reading, and that threw me off. When I get a chance I'll give it another shot I guess.

Not familiar with your alarm, but unless it has an onboard relay for trunk release it's a ground. If it had an onboard relay you wouldn't need the relay to begin with...Mike M2

Yeah...I should have gone with my gut and assumed it was negative. I had my circuit diagrams drawn like that and it was hooked up that way and everything before I tested it with the multimeter and switched everything...I'm just an idiot. Thanks for the help.
