Question fuel gauge wiring diagram

I have an 87 ford f250 with a 4.9L and cannot find a wiring diagram to install a digital fuel gauge. truck has dual tanks with selector switch. I have two new fuel sending units to install once I figure out what wire to attach to the new gauge. I plan on using a dip switch for the main power instead of using the accessory wire. I have a Chilton manual but there are not any wiring diagrams listed.

need help again

Thanks to lazy k I got the fuel fixed now I need help figuring out why my truck does not move. Today I was driving and went to shift into second gear and something popped and blew a puff of grayish smoke and now it goes into all gears smoothly, but does not move. I have a Chilton manual but it is not helping. I really hope I do not have to change the tranny. What could be all of the problems that I can start with before I dismantle the transmission to install a new clutch. 87 f250 4.9L 4 speed trans. I am totally lost and really ned help before I have to put it into a shop.

If 4x4 check that the transfer case has not jumped into neutral. Also check if it moves when shifted into 4lo.
However it may be that the splined hub has sheared from the clutch plate, would need to pull the trans to check that. Could also be that the pressure plate has failed.

truck looses power while driving

O am losing my mind trying to figure out what is wrong. When I am driving once the truck is warmed and cruising it starts loose power until I hit the gas and it runs nice until I start even out at any speed. This happens only when I get about five miles or so every time. There is what I have done to fix this problem.
I have changed plugs and gapped them properly, new plug wires, new water pump and thermostat, new intake seals exhaust seals, valve cover gasket, EGR gasket, new vacuum lines, new power steering pump, new oil pump, new clutch, new high pressure fuel pump, low pressure front fuel pump. 2 new fuel filters, oil filter, new oil, and fresh gas. I also cleaned each fuel injector and they work fine. I have checked all fuses and relay's and they are good. One thing I have done was when I bought the truck I took of the PCM and found that there was a bad 12.00000 MHz crystal that was corroded and broke. I purchased a new one off of the net and soldered it in. I am not 100% sure that is the right crystal but it made the truck start to run. Is there anything that I could be missing and can change?

!985 Ford f150 Truck

My fuel gauge is always saying empty also. Repalced intake fuel pump twice. The 5 Amp fuse keeps blowing for the dash lights every time I replace it too. Any suggestions?
