It has fried 3 relays in the last month.

The entire EFI circuit doesn't really draw that much current (roughly 6.25 amps protected with a 15 amp fuse), but poor contacts will cause arcing at the terminals or poor crimps will cause a high resistance. These are replaceable parts with pigtails that can be spliced in.

I thought about moving it , I haven’t seen that done anywhere though. If it made the problem go away, it would be worth it.

How did you secure it in the cab?

 

[Marco Lau]

just zip tie it with all the relays behind the kick panel in the driver footwell.
