Is this procedure required on cars of all years or only the earlier ones?

In the US, only the '93 and earlier cars run the fuel pump wiring through the AFM. Later ones have the ECU control it directly.

Yep. My fuel pump for my 94 is controlled through the megasquirt, PNP.

So.. I know we've talked about the fuel pump wiring being accessible under the dash... it is... and very easily. No need to run outside to the diagnostics stuff... or jumper that fulltime for your fuel pump.

Just run one wire from the MS harness over to the driver side kick panel... its all there... here are the pictures that "guide" you to the wire.

The wire is light green.
So... start by heading for the hood latch area.

Now lower your head to the floor... and start peering directly behind the hood release area.

Back there there is one plug you want....

Close up of it



Simply tap that wire for the fuel pump control out of the MS. Works fine... you'll get prime on initial "ON" position and then fuel pump while on. At least... I know mine primes and shuts off before cranking.
