really max, it sound like you've got you work cut out for you....It could need a heck of a lot more than that!!!
back up lights- in the neutral safety switch on the transmission. Ohm out the switch and if both the neutral and back up parts of the switch work, its in the wires. BEFORE you go and tear them all out tho.....make sure both of your bulbs are good
(i know this from experience
)
headlights- You should probally just go and get two new bulbs anyway, start off fresh.
blinkers- could be a couple of things....1) in the switch behind the steering wheel 2) wiring (again, check bulbs) 3) improper ground, connections.
I had my in-hood turn indicators not work b/c the ground was not good enough...
with all this electrical, check fueses, connnections, bulbs etc. first.
I don't know if you have any mustang restoration junkyards or stores anywhere near (you should, cali is crawling with stangs)
if so: It shouldn't be too hard to get a vacume booster for the brakes....
and now the steering......
you said its sloppy all over, the best thing to do would be to take it to a shop, align it, check the tie rod ends, all that good stuff. Or do it yourself, I guess you never mentioned what kind of car experience you have??
and then for power steering, I'm not quite sure with your serpentine setup what you need to do, but baisically all it is is a PS pump and a hydraulic ram, rod ends for it etc.
again, if you have a shop nearby, your much better off.
but what about you???!!! any past car experience, for all i know, you could be Jack Roush under a different screen name!
ps. the tech section is crawling with help, and knowlegeable fellas, posting there might wield more results.
happy to help!
