i have an 85 capri and i have everything motor wise hooked to a switch in my car as in fans, fuel pump, ignition box, and fuse box and my ignition isnt hooked to the factory key either so my question is how do i get power to my fuse block for my turn signals head lights and tail lights. the guy who owned the car before me had so many aftermarket wiring it was rediculous. im not the greatest at wiring but i make it look purdy. btw i have a lot more questions. so far i took the heater core out. could i make it easy find out what wire provides the power to the factory harness or fuse block and hook it to my ignition on switch??? i need some sort of guidance. please and thank you!

just came across this.... maybe it will help, not sure because it did spend a lot of time looking through it.

Ever take your car to the track ryanw?

and would the power to the fuse panel come from the ignition switch then to the battery and could i test it by giving each wire in the connector power and checking the fuses with a test light???

On my car, I believe the fuse box gets all of its power from the solenoid including the ignition. So im guessing you have wire not hooked up to your solenoid.
Just an fyi.... I think most knowledge about fox body mustangs are known from 87-93 . Info gets a little sketchy from 79-86. My point is, your not going to get as many responses to your questions because we dont know a whole lot about those years. Well that seems to be what I see any ways. My advice would be to join a few mustang forums and post the same questions on each forum. Some questions we can answer and other question might be answered on other forums.
There is corral.net, also , foureyedpride, stangnet... ect... ect....

ok so i took the bottom cowl of the steering column off and i saw a connecter going to the ignition key so i figured why not poke around in there so i took a test light and ran a wire to the solenoid and low and behold i found 2 wires that when i hook power too all my lights work, one that just clicks and another that was dim so i hit the window switch and it got bright but the window didnt roll down or the doors didnt unlock. im thinking to just taking the wires that lead to the ignition switch and hooking them to my ignition on switch on my little switch panel. will this be ok or how many amps does the switch need to handle. and idk how im going to get the windows to work. im confused
understandable, i found what gives power to the windows now so basically everything i need i know what to give power to. so how do i hook that up because theyre like 12 guage wire and there is 3 of them. i could put another ignition key in it and run hook them up to an accessory on. would that be a proper way to turn the accessories on and start the vehicle right?

Not knowing how the 85 mustang is wired, if I had to take a guess this is how id do it.
Take a relay.
On the coil side of the relay. One line to ground the other side of coil ( normally open) to ignition switch, that way the widow will only work with ignition switch set to on.
The high voltage ( non coil side.) One side runs to the switch on the door and the other runs to the solenoid with and inline fuse or circuit breaker rated for that specific device ( at the solenoid)

No track time yet. Maybe in a year though. Vary busy these days and some incomplete projects. Saving for a house and the wife just gave birth to our second child, so I have no time and no money.

I was just giving you an example of a relay. The ones I work with doing a/c work come in many different types.

Make sure you use good wires, ( the correct size wire and fuse) solder where needed with shrink tubing. Then add some protective wire loom and zip tie every thing nice and neat making sure nothing is rubbing against any of the body
No speaker wire.... my point is... do right the first time

Grab a Haynes manual. They have wiring diagrams for 79-93 Mustang and 79-86 Capri (the wiring is the same). The 86 models start on 12-21 and end on 12-32. The print is small and tough to read in places but can be figured out. The printer got lazy with the fuse panel, but there is enough of it there to figure it out and finish what the printer missed. I have a 93 so it wont help me out, but i fixed it anyway using a ruler and a pen (start with a pencil) with a very light touch. Its not the best wiring diagram out there but it does come in handy, its better than nothing. It does not however tell you what gauge the wires are.
I would wire the thing back like original.
All your heavy loads are on the switch you added, so I hope it is adequate. It is pretty tough to find a switch that can handle fans, fuel pump, ignition box, and fuse box.
The fuse block has two power feed wires. One wire is steady 12V (hot all time), directly from the battery lead at the start relay battery post through a fuse link. The other wire is switched 12V (hot in run) with the key.
You are going to be in a royal mess if you don't restore the large yellow wire that goes through a fuse link to a red wire that connects at the battery terminal of the start relay.
There are two basic power circuits. One is hot all the time to multiple things from the fuse block, the other is multiple circuits switched through the key. Most of them are from the fuse block.

I understand. People can really mess up wiring for the next owner. Cars certainly have complex wiring, and people are usually hacks.
The important thing is it doesn't leave your stranded, and doesn't start a fire or damage the car. The OEM wiring puts a lot of care and planning into not melting people or cars down.
