92 Cheyenne 4.3 5 spd to 305/700r4. HELP!!!!!!!!!

[SSmith]

Hi, I have a 92 Cheyenne that was 4.3 5 spd, I swapped in a 305/700r4 with all the wiring except the rear portion of my truck. So the fuel tank and taillight wiring is 92 and everything else is 89. With that being said I’m trying to figure out the fuel tank sending unit wire for gauge for the level of the fuel. I have tried every wire that I’ve found on line that is the sending unit wire, I’m installing digital gauges and can’t get the fuel to work. I have a Intellitronix dash for the 88/92 obs. I could use any help available. Thanks!!

Where are you checking for the wire? If I remember theres a flat connector below the booster at firewall and it should be purple.

To what booster are you referring?

I was planning on dropping the tank. I’ve just been checking on the plug for the gauges

The brake booster

Is it purple all the way to the gauge if you know??
