spark plugs and cables which order do they go

While driving the gas pedal stopped working, and we just coasted off the road with engine still running at a regular idol. I shit the engine off and now it won't start. I have changed the TPS and the fuel pump seems to still kick on.

Mechanic charged it two years ago. Had a little problem getting the clutch to engage. He fiddled around a bit on the compressor and it worked. Getting the same symptoms now after I charged it with the kit that I bought. Does the clutch have a separate relay to engage. The compressor turns okay. Did a little reading online would like to perform some tests to see if I have to change the compressor. Where do I find the clutch relay If there is one and the low pressure switch . Which could be the problem. As it stands right now is blowing warm air with all controls at full throttle.

I installed a Brand New Transmission, Oil level is Perfect, installation was Perfect too, Everything is Connected but she doesn't shift from 1st gear, Any Suggestions Please!

Interior running lights do not work. There is no apparent fuse to place for this problem. The lights were working and then not sure what changed but they don't work anymore inside.

The light is on. Mechanic is checking the wheel while the parts store says it is located by the transmission in a black box.

I recently had the automatic transmission rebuilt. The engine revs and the transmission does not shift out of 1st to 2nd until 20 MPH. The tech says this is about correct. I sense that the engine is reving too much in all the gears when shifting up. What are the approximate proper shift points from 1st to 2nd, 2nd to 3rd and 3rd to 4th in MPH?
