Electrical problem plug in the drivers kick panel

[Mindseye007]

need an l electrical wiring diagram for a 1991 5.0 coupe, need to figure out the plugs behind the drivers kick panel...there is a big black plug that melted a little and the pink wire with black trace needed to be cut and reconected and bypass the black plug for the fuel pump to prime when you first turn the key to on posistion and the pump primes for a second then you start can the car up. i think my 340 lpr is putting out to much juice and frying the black plug and my radio when my kenwood double din stereo is on when i go to turn the key to on posistion the pump will prime and afew times it did not prime so I press the the button on radio to turn it completly off then turn the key back to on the pump primes. and the car starts . going to get a 190lph pump i think. I only have long tubes and explorer intake, 76 mass air, 70 mm tb and stock cam and heads or should i buy that heavy duty wire upgrade kit for the areomotive 340lph from LMR https://lmr.com/item/AMV-16307/aeromotive-heavy-duty-fuel-pump-wiring-kit
I had the 340 installed back in 2018 I dont daily drive it only on nice sunny days and store it in the winter time not sure how much life is left in the 340, should I change the 340 with a new one? or just downgrade it to a 190 or 155 even? I was saving for heads and blower and I still am saving lol ...

here is a pic of the black plug not from mine but the exact plug i am talking about and some one else had a simlar problem , where can you buy this plug from?

No time like the present to buy the EVTM and wiring diagrams for the car. I believe if you look around you can buy them with an electronic download.

I looked on here and could not find one but maybe someone will replay and be able to share one with you.

As for the size of your pump. What you will spend on a new pump you could just wire the car up for the 340 and not take any steps backwards. Just my .02 worth.
