Which brake line are you talking about?. The metal steel ones,or the rubber ones. Doesn't matter. If you are buying the rubber ones, then just ask for them by year and model of truck.

If you are working with the steel ones, they are either going to be 5/16 or 1/4 depending which line it is. the 5/16 ones are usually attached to the master cylinder or the ABS unit. The fittings sometimes if you don't find the right one have to be re used, in which case you will need to flare the tubing. (Double Flare) Or you can go to the dealer, pay an arm and a leg, but you don't have to flare the tubing, which takes the fun out of the job.

on the brake calipers ther is a bleeder screw. It looks like a grease fitting.1) fill brake fluid 2) have a helper pump the brake pedal ( vehicle not running ) 6 - 8 times to the floor and release then press pedal to the floor and hold with foot pressure pressing down. 3) at this time loosen the bleeder valve and the pressure and air will release,( do not allow brake pedal to release or come up, continue to hold to the floor ! ) after pressure and any noticeable air bubbles and no more fluid comes out then this is the time to tighten or (close ) the bleeder screw. 4) continue this process untill no visable air bubbles are present, IT IS VERY IMPORTANT THAT YOU CHECK THE BRAKE FLUID RESERVOIR AFTER TWO BLEEDINGS AND FILL AS NECESSARY ! 5) Continue the procedure on the opposite side. Do the two front wheels and the rear wheels as a pair as the brake system is a two part system, FRONT & REAR

There's a A/c clutch relay if that's the one your looking for. that relay is located in the power distribution box located in the engine compartment (see picture below). The relay that I am talking about will be in the number 204 position (see picture of layout below). This should be in your owners manual if you have one. If you need an owners manual for your vehicle, email me at [email protected] with your make, model and year and i will be happy to email you one. Don't worry it won't cost you anything. I hope this helps you and good luck.
