86 Iroc 5.0 TPI Burn Off Relay Mass Air Flow Help

I have searched the forums and the internet and can not seem to find a new Mass Air Flow Burn Off Relay. I know that there are 3 relays on the driver side firewall. Mass Air Flow Power, Fuel Pump Relay and Mass Air Flow Burn Off. I know 2 are the same and can be interchanged. I believe they are the Mass Air Flow Power and the Fuel Pump.
Does anyone have recent part numbers for these relays and where to purchase ? O'Reilly's has a listing for the 30amp Fuel Pump and the 30amp 5 blade Mass Air Flow Power.
I am stuck on the burn off relay. Thanks for the help.

Pete

It's a relay. An electrically operated switch. Nothing more, nothing less.

No need to get all wrapped up in "burn-off", "lists", and all of that. Kinda like, in a general way, asking what brand of switch you'd need to install in your living room wall, if you just installed [insert brand here] bulbs in your lights. It's just a switch. Beyond making sure it switches when it's told to, there's not much more to it than that.

It's a 5-pin if memory serves, butt you're looking at it so you know better than I do; if it's a 4-pin, then that's all you really need. The current (amps) is pretty low in all cases; like, less than 5 amps. So a relay "rated" for 30 amps will be fine. Or 40, or 10, or ... anything greater than 5 amps. Look for one that your plug will plug into. If it does, then it'll work just fine. 86 AFAIK would be the older square-ish style as opposed to the newer oval style, butt hay, if you can get an oval relay and an oval pigtail to match it, you'd be set, as well.

Not sure why you think you need a new one, unless you lost your old one or something (that relay doesn't go bad all that often because the stress on it is so minimal, butt who knows, anything mere humans make can "go bad" just like the humans themselves sometimes do); butt it's just a relay. Not that hard.
