As well as the Pigtails? When I search two relays come up a 30 Amp and a 20 Amp. Which one should I use? Also I can't find the pigtails at all. My car is a 1986 Camaro IROC Z. I know later years used a different shaped MAF relay but mine uses the rectangle shaped one. My wiring on my pigtails is really bad and I would like to replace them ASAP. Here are some pictures if anyone can make out the part numbers and see how bad my wiring is:

Closest to Engine Block.

 

GM 10067925 MAF
GM 10094701 MAF BURN OFF
GM 1407814 FUEL PUMP\
You can use the burn off relay for the fuel pump relay and vise versa

 

Thank you. According to Rock Auto, the 30 Amp relay is the MAF Power Relay.

However, I can't find the Burn Off or Fuel Pump save for old eBay listings. Are the Fuel/Burn Off relays the 20 AMP from O'Reillys?

 

Ok so I replayed the MAF Power Relay with part RY31. It's the 30 Amp relay. It seemed to make a huge difference. The rough idle at start up and when braking is gone.

Now I'm not sure which part is MAF Burnoff/Fuel Pump relay. Maybe I'll be that 20 Amp relay and see if works. Does anyone know what relay you used recently, since the park numbers no longer work.

 

Have you tried TPIparts.net? They may still have the relays.

on the 86 Trans Am the fuel pump relay was in the center of the three relays,the burn off was to the left of it and the MAF was to the right of it

 

I know where they are. I already replaced the MAF Power relay. I just can't find a Burnoff or Fuel Pump relay. None of the major auto parts stores seem to have it and Googling the above part numbers only gets old eBay listings or old forum pages from the 2000s.

 

Good news is they have the pigtails bad news is no relays.

 

Rockauto has relays that look the same listed under Fuel Pump / Circuit Opening Relay:

WVE 1R1240 and Standard Motor Products RY121.

Might want to confirm those are for your year.

 

I think WVE 1R1240 is the right part. I'm going to order 2 of them.

 

I just finished splicing the pigtails that I got from TPIparts. Quality stuff, I highly recommend. I replaced the relays with NOS stuff (made in USA) I found on eBay, I'm not sure about the China stuff but it may be just fine.

 

Awesome. I'm going to order those this weekend.

 

 

You can update to weatherpak relays and pigtails lookup 89 Vette or f body.

 

The part number I do believe is 18987625 but I can't be for sure anyway try that hopefully it will help you
