Can I test the pump in the car? If so which wires/pins do I supply 12v and ground to? There are 4, a large grn/wht and large brn on each end and a smaller prpl one and brn one in between.

I saw the Pelican DIY for the fuel pump replacement with the info for jumpering the relay but the picture and written instructions were different. The instruction said jump pins 30 and 87, but the picture shows 85 and 86 jumpered.

Doesn't matter, I tried both but never heard the pump

Also, when i removed the cover under the battery, i noticed that there were 3 smaller wires intentionally cut. I think they go to the pressure sensor maybe? Either way I haven't noticed anything while driving, not sure what they are for.

Thanks
