Engine Start Button and Starter problem

[Neejay]

My semi-mechanic installed a button underneath the dash that goes directly to the starter, so I have to push it while turning the key to get the car to start.

Well when I was trouble shooting why my car wouldnt start (later found out it was the starter and the button just prolonged the failure) I moved a wire that went from the button to a fuse. Now I have to hold the button down, and the key turned while nothing happens, then after holding it and re-trying for a while, it will eventually crank and turn over without any hesitation/problem.

When I hook back up the original setup, nothing happens (regular key turning). What fuse should that wire be going to? Or is there something else wrong?

EDIT: I did some more searching and found this:

It's the simplest thing in the world. All you're doing is using a button to start the car instead of turning the key one more position. Ignition on, wire the button to the black/yellow feed at the key switch to trigger the solenoid. Some kits come with a low current switch and relay, other just use a high current switch. Follow the instructions that came with it, whichever design it is. Do NOT use the orange wire to the ECU, that is a signal wire only.

So does this mean that I won't need a relay in there if I wire it too the black/yellow feed? Or is this the "high current switch" only?

Then I found this:

I do NOT recommend the high current setup. Because most push button can not handle the amount of current through the button itself it will melt. It can also cause a short to make your starter stay on. Best way to do it is to wire it through a relay.

This is EXACTLY my problem. I think it's wired with just 2 wires: starter and another one was attached to a fuse (forgot which one though). My starter wouldnt cut off, and since I had to keep it on to move the car, it eventually just cut off while we were moving the car. Is my starter fried?

So Im confused. Where exactly does the relay wire in? I couldn't find any pics, as that would help a LOT.

And if you have a diagram or take the time to explain/show it, please do it in SIMPLE terms (i.e. red wire -> relay -> starter) I dont know **** about electronics/wiring.

EDIT x2: Does this look about right? (the top part is from the FSM and the bottom part is a button by pivot, but I dont necessarily need touse their button, but its a good representation):

Is there just a wire going to start button and a wire leaving? If so, that would be 12v positive going to starter. the button just interrupts the wire. when you depress button, the wire is connected and 12v positive goes to starter. if you hold button tooo long, you will burn out starter.

if there is a relay, you need positive and ground to energize relay coil which closes relay switch. When relay switch is closed it is the same as pushing button. the 12v positive going to starter is connected. i can't give you any advice as i have not done this in a long time.this explains how a relay works.(if you dont know how use a multimeter, you probably shouldnt play with this)

DAMN, FINALLY. Thanks a lot man. That's what happened exactly. I had to hold the starter down for some reason looong periods of time before the starter would start turning. And yeah, there was just one wire going to the starter, and another going to a fuse.

Does that pic I posted look about right? (probably won't use the same fuse/colors, but in general)

I assume the start button is for security? Here is a diagram that uses two relays for start button. This way, i assume, you are distancing yourself from the high amps that go to the starter motor.

keyside and motorside of starter would be the two wires that go to your current start button. these would be a thick wires. the ground and 12v positive is just to close the relay switch.

hmm...Im trying to understand it. I think I need a mspaint version

EDIT: Ok, well I need a diagram for just one relay.

Bump...still not understanding.

I have a 30am relay already (happen to have one already with a plug/harness):

30 = Thick Red86 = Thin Red87a = Black85 = White
