I am look at this article here..
http://forums.trailvoy.com/articles....ticle&artid=37

In here clearly explains that I need a 5 pin relay. (85, 86, 87, 87a, and 30)

The only issue is that my small town only has a 5 pin relay with pins (85, 86, 87, 87q, and 30)... I am not sure if these are the same relays.. would anyone happen to know if these would be the same or should I just... buy one online??

Hmmm, I am not familiar with pin 87q.

If it's contact closes to 30, the relay is probably the same as one with a 87a

Pick one up from Amazon - free 2-day shipping if you have a Prime account. (if you don't and you want it quick from Amazon, you can paypal me the money and I'll be happy to send it to you since I have Prime).

I was able to get the 2day on that relay, but when I looked at both relay diagrams... they were both the same:bonk:... oh well.. at least I have another relay if anything.

Thanks everyone for your input.

Probably something in the physical make-up of that contact, perhaps the contact plating, perhaps the spring pressure.

Nothing to make any difference in your need.

I believe the 87q relay will work fine. It may be a relay with a diode in it which is good. The diagram on the relay should show it.

A 5-pin relay is often referred to as a change-over relay....
