Long story short, my brother had truck sitting, someone tried to steal it, ignition is wrecked, he needs it gone, sells it to me for $50.

I was thinking of bypassing the ignition switch in this manner.
1 - Find B+ from ignition switch
2 - Run B+ to toggle
3 - Run four seperate wires from the other side of toggle (ecu, acess, misc, starter)
4 - Run three wires to individual relays (3, 40A bosch relays)
5 - Wire the ecu, acess, misc on their own relay
6 - Fuse each on the B+ lead on the 4 wires
7 - Run the fourth wire to a 15A momentary push button with starter wires on opposite side

The ignition switch is a pain to replace, you must remove the column, I am not going to do that, will this method of wiring work? Anyone see any problems? Thanks.

I wont be able to leave anything on you have to flip the toggle switch down to shut the truck off, it is one toggle switch on the acess, ecu, misc (not sure if there is a misc), and a momentary for the starter wires.

It wont **** **** up.

The truck is a 90 F150.

Optika1 illushun, My brother is two and half hours from me, when I looked at the column last time I was there, there did not appear to be any screws around the cylinder. It seemed to be a one piece mold. I looked the ignition switch up on Alldata and it showed removing the complete column. He had revieved estimates around $500 to have it fixed (I would assume a new colmn, but not sure).

pontiac4evr_14, any chance you could ask them on how they wired it?

Thanks.

If you don't plan on replacing the ignition column then you are just waiting for somwone to steal it. OR just use it as a daily driver and never add anything to it, cause if you do and they want whats in it then they will just drive the truck away and take there sweet ole time pulling stuff out.

Its just going to be used as a daily driver and work truck (until I get my grand am fixed), I don't plan on keeping anything of value in it, the latch on the back window is broken from when they tried to steal it. I will add a kill switch underneath the dash (not the most secure, easily bypassed, but most won't take time to find it). The truck is a 1990 F150 with sun faded paint, I bought it for $50, if it gets stolen its not the end of the world. I don't see that as being an issue though as I live in a small town and in the country. If they were smart enough they would have stolen it the first time, also the truck is sitting with the brake lines disconnected at his house so if they try to steal it again they will hopefully die.

it seems to me it would work fine

you could just get a battery disconnect, with a key switch and mount that somewhere

battery disconnect = to a key switch correct?

I will put the key switch on the B+ before everything else, I don't think it will have to be a high amp switch.
