Instructions IN DETAIL ,for the wiper **** & headlight shaft/**** can be found by searching those exact words for this forum as they have been asked numerous times.
What do you mean by Back light ?
Rear lights,dome light,back-up light, brake lights ?
Be more specific

Check your dimmer switch. The little arm that touches the armature? (I forget what its called). It looks like a spring and its what twists around when you dim your cab lights and what not. Someone help me out here on what thats called. Do your gas and temp gauges ever stop workin?
On the wiper **** there is a metal tab that you have to pull forward with a pair of small needle nose plyers. The shaft that the **** sits on is round except for one side that has been flattened out, thats where the top of the tab should be. (should be facing up).

See terminology is everything.
Those are called the *instrument cluster lighting*
It's not a tab,
On top or bottom of the plastic **** near the dash is a little 1/8" slot.
Put a small screwdriver in there (as the friction holder spring needs to be slackened so you are taking the pressure off the spring) and pull forward toward the seat.

73-79 Instrument cluster removal
1) Disconnect Battery.
2) Remove radio *****
3) Remove two screws under radio bezel
4) remove instrument cluster bezel screws
5) Put transmissaion in Low gear.
6) Place towel on column to prevent scratching
7) Pull headlight switch to headlights on Position >
With Right side of bezel loose reach in to top of headlight switch and depress button while pulling the switch **** out all the way.
8) Remove Wiper **** (Take a jewellers screwdriver and poke it up in the slot,behind the spring metal clip.
Pull the **** with the screwdriver against the clip towards the seat.
Voila ! It slides right off.
I bent a small screwdriver with a 90* bend on the tip to use for that purpose.)
Unplug light to wiper/washer lens
9) Undo the 4 screws that hold the cluster.
10) If your have cruise control> disconnect speedo cable from speed sensor under the hood. If you don't, go directly to 11
11) Grab speedo cable retainer and squeeze the keeper.
12) Pull cluster toward you and lay on towel.
13) Grab the tangs at both ends of the cluster connector and squeeze & pull out.
14) Have a sip on something cold

Thanks so much for the help,you guys are life savers.I found a cluster at a junkyard for $75.Is this a fair price.I seen them at "BRONCOGRAVEYARD" for about the same,but I am sure theirs have been tested.Is there anything to look for (besides not crumbling into a million pieces) when I pick this part up.Also they have a real nice dash pad for $45 that I need.
Just started to dive into this truck,I known I need a bed and floorpan,other than that the truck is pretty solid.Down the road i am going to swap the I6 for a 302.It has a three on the tree,and i was wondering how hard it would be to make it a floor shift, can i use the same tranny or is it a different set up all together.
is that enough crap in one post or what. THANKS AGAIN FOR ALL YOUR HELP!!

There are 2 kinds of clusters.
14 pin *Idiot light* cluster
or
18 pin *Gauges* cluster
That price is comparable.
Look the whole thing over very well.
It sounds like plastic in your neck of the woods tends to rot from the heat.
