my metra roadwork aftermarket antenna relay its shot and will not let the antenna go down. the antenna goes up but not down and i cannot find the original 5a/30vdc godsky 202-d relay. it is possible to use a regular spdt relay? can you guys help me with the wiring since i'm not sure to which of the post in the relay i have to plug it. thanks

To do that, it's probably 2 separate relays isn't it? (2 x DPST or DPDT?)
You need to imitate the centre-off polarity reversing switch (assuming it's a 2-wire motor; if 3 wire 2 x SPST should do).
I'd expect an appropriate diagram in the relay (circuits) section....

i'm still confuse on how to hook it up, the power antenna has three wires and i removed the factory relay and found it to be burn. the anteena stay in the up and i need to know if and how to hook it up to a relay so i can get it to go down. or if i can use a toggle switch. sorry ,but i need a more specific instructions on to what goes where. liked antenna wire go to the different locations on the sp relay. thanks for any help.

You'll need to tell me what the wires are.
I assume one is GND (probably black) and the other 2 are +12V as required - one for up, the other for down, but NOT both at the same time. (IE - connect the GND, then with a +12V wire, try each "other" wire one at a time.)
You could test that. I suggest using a 10A fuse in the +12V line.
