hello.

i'm working on removing key cylinders for my doors (completed) and ignition.

i already have a keyless entry alarm system that i had to learn to install myself. my end goal is to learn about wiring basics and relays are where i'm at right now. i wired the relays to my door locks but i guess that's not enough relay work for me to remember by heart.

ANYWAYS! below is a diagram of my ignition system. i have a diagram for the starter button (does not incorporate a connection with WHT (BAT -a).

i am left with wiring the ACCssories (I) and the ON (II) switch to a three option toggle (off, option a, option b)

how can i acheive this with the least amount of relays? thanks for any input.

sorry for my noob posts, but if you have an idea just label the wires A-G

You should be able to do it with 5 relays (one relay for each switched wire) and 9 diodes. The diodes will prevent backfeeding from position to position.

relay coil A = WHITE/ black

relay coil B = WHITE/ blue

relay coil C = BLACK / YELLOW

relay coil D = yellow

relay coil E = BLACK/ white

So -

Switch Output 1 --> Diode --> relay coil A

Switch Output 2 --> Diode --> relay coil A

Switch Output 2 --> Diode --> relay coil B

Switch Output 2 --> Diode --> relay coil C

Switch Output 2 --> Diode --> relay coil D

Switch Output 2 --> Diode --> relay coil B

Switch Output 3 --> Diode --> relay coil C

Switch Output 3 --> Diode --> relay coil E

Then you would just need to make sure the correct output is wired to the correct battery source.

nice, thanks! i've never worked with diodes but i'm going to look that up. is there some kind of rating i should look for? i'll be reading up regardless, thanks much again!

1A diodes will be adequate for your application

Anyone thought about (possible) factory transponder, steering lock etc etc etc. Fun, possibly expensive, lots of extra wiring etc. etc.

hopefully this will work. thanks for the conformation.

i'm also in the market for a single toggle switch that can handle both "ACC" and "ON." i'm just not sure what the tabs for wire mounting would look like. would this switch be called a dpdt?

also, what websites are good for relays and switches? i'm in elk grove california and there is not anything local with a reasonable price. the only thing radioshack had in stock were spst relays for $7.00 plus tax (CAlifornia) a piece!? i remember getting them for less than $5 from autozone and those came with pigtail harness' for the relay AND were spdt!
