Not entirely sure I'm tracking Tom. Is the box in one of the pictures posted above? If so I guess they are their own special relays and aren't backwards compatible. Otherwise I honestly have no clue where they're at. There is only one relay mounted behind the hood hinge so I can't imagine it is relevant in this context.

Ohhh okay I got ya now. Yeah I had just pulled one of the relays out of that empty plug - there's only the two under that cover. So I know where they are but that won't help any - the relays I got are too big and have different plugins than these. Maybe '88 was a special year with special relays?

The top relay is one of the two 1988 relays I pulled out of the relay box. The bottom relay I took from my 1996 truck for comparison. The 1988 relay plug is a different configuration and is dimensionally smaller than the 1996 relay. Unless that top relay has to be disassembled further, and then oops dumb me strikes again.

What would make me inclined to agree with you is that the 1988s and 1989s use the low pressure in tank and high pressure external fuel pumps, so maybe those relays are different than the 1990+ FDM type?

Gotcha. Thanks Tom and Vinny. Glad we cleared that up. Gonna get rid of the universal relay and get me a Ford one.
