I need to replace them and I looked and I think I have one on my passenger side front behind my C canister and i have 2 that look the same on my driver side firewall. The guy brought out 2 of them and I have 3 that lok the same which ones do I change?

 

If it's a chicken, they are on the firewall on driver's side. Not sure about the 'maros tho.

 

Its a formula are both of them side by side? Whats the one by my air cleaner?

 

On my camaro 89' iroc, Next to the Master cylinder and power booster there is 4 switchs. One of them is the (1)ESC module, (2) MAF sensor Burn off relay, (3) fuel pump relay, and (4) MAF sensor power relay. It should go from Passenger side to drivers side 2, 3, 4, with the ESC ( a fairly flat square piece with a long narrow plug) behind number 2.

The sensor by the air cleaner i believe is the Primary Cooling fan relay.

Hope you can make sense of that.

 

Mine are here:

On my 2.8, there's a MAF relay on the passenger side of the radiator support. Wires go from it, to the MAF fuse on the framerail, to the battery junction block, to the MAF, and two wires lead back to the computer. Of course this is a 2.8

The relay you're probably seeing, Mkos, could be for the flip-up headlights.

A picture speaks a thousand words. Which is way more helpful then my explanation.

 

damn y cant mine look like that. Is the MAF Burnoff and MAF relay look the same? With mine i have the ESC then a squre relay with like brown jelly in the connector then i have 2 IDENTICAL relays next to that (with like the ovel connectors) are those 2 the ones i change?

 

Ok then you have exactly what i have. That square relay is the Burnoff relay, the oval like one next to the square relay is the fuel pump relay, and then the next oval on is the MAF power relay. So it should go in order from passenger side to driver side
the Square one(MAF burnoff relay), Oval one(fuel pump relay), Oval one ( MAF power relay). If you are still un sure go to your local library and grab a repair manual on your car, that should show a diagram of where the relays are.

 

When I went to the local Pontiac Dealer the guys said the Burn off and maf relays look the same? WTF?

 

The relays are identical and have the same part number. Most auto parts stores only list one of the two parts. They are the same though.

 

so are they the ones right next to eachother?

 

It's possible. All my TPI cars were set up like Vader's pic though. The latest model I've owned of third gens is my '89.

 

Vader's relays dont even look like mine. Mine are ovalish. Well i found one relay. I unplugged it and it through a code 33 so i know that was one to change. I'm still looking for the other. The manual says it has a Red, Blue ,BLK/WHT , Orange , and BLK/PPL wires but i dont have the BLK/PPL mine is TAN/WHT

 

Mkos, what year is your car? I'll call the place I got mine to make sure yours are the same as well. Last time I looked in the book, they both used the same part numbers for '86-'89.

 

Mine is a 89 350 Thanks Alot

 

Help. After 4 years I still dont know and the code 33 just came back after all these years. I have the ESC, Square relay, then 2 ovalish ones. Which are which?

 

try this:

 

I read where you said yours look oval compared to the earlier pic by Vader, so I looked at the delco website, and the pic of the relays for '89 are oval, not square like earlier years.
