I wonder if this one would work. The prongs all seem to line up. It is just missing the one in the corner.

This thread says a 4 or 5 pin relay will work if the #86 pin is trimmed to fit.

I will have to look at the wiring diagram. Any 30A or higher relay will work. You can trim like you said but the leads are coated so if it is used i would be careful (did not read link as on phone).
You can buy any auto relay and buy the pig tails and you can plug the pig tails into the relay location.

I know its an older thread but I found this and I do need the fuel pump relay for a 98 Viper. I am looking at these 2 generic relays but I don't see how can you use the 4 or 5 pin relay in place of a 6 pin.
The oem has 6 pins. I see the width of one of the pin needs to be trimmed, that is ok but it looks like the oem has 4 rows of pins and these have 3 rows.

The relays are dirt cheap, so get 3. Dremel on the 6th pin to narrow it down. Practice on one, then do 2 more while you're at it and have the touch going.

Just match the pins from the new one to the old one. All of those relays have the same pins numbering as a auto standard.
85 + 86 = coil
30 = common
87 = NO (normally open)
87a = NC (normally closed)

If the factory relay has a diode across the coil YOU MUST USE a relay that has a diode across the coil too. Else you will introduce high voltage spikes back to the pcm on discharge of the coil.

I always added a diode on my designs if the relays didn't have one built-in. This is standard practice.
