So we need to cut C-214 pin 13 and use that in left relay pin 86. The other end of wire, connect that to left relay pin 87. Keep rest like your drawing.

So your left relay is the new Relay #2.

 

Well you wouldn't want to cut that, because then you would kill the whole factory circuit. Im not even sure that wire is useful because i think* that is always hot.

 

That's the power wire to Relay #3

 

C-214 pin 28 is on the same circuit as C-210 pin 1, which is the circuit that provides power to stock relay coils, so it looks like you could tap that at either connector.

 

yah thats right, its the main power wire for relay 1, 2 and 3. You would want to leave that alone unless you wanted to bypass the entire stock system.

 

We use it as a signal to turn on our relay. It will control our left relay, so our left relay essentially becomes the new relay #2. You connect the other end (that goes to Relay#3) to 87 with the power to right relay.

 

I was looking at it backwards lol, thought that was the input side. I get what your saying though, that would work I wanted to keep that factory copper in the loop though so I probably wouldn't interrupt the factory circuit that way, but yah that would work just fine, good idea.

 

So we are basically doubling up on Relay #3 and replacing Relay #2 so we don't burn out the OEM Relay #2.

 

Looks good to me

 

Perfect. That's what I'll do tomorrow.
I'll have to rearrange my wiring.

Actually, I'll double up on right relay by adding a backup right, so if first fails, backup will kick in to power pump and light up a LED bulb to tell me to replace relay.

 

gluck I know I always have a good time climbing upside down under the dash to do wiring On the plus side taking out the drivers seat is pretty quick and makes things a lot easier.

 

Uhh I would be careful about triggering 2 additional relays instead of just 1 extra off that ecu input. The fet might be able to handle the extra current but you might be pushing it. I posted a few pages back what the specs where on that OEM driver fet. If you do want to try it though you might consider getting the relays with the built in flywheel diode so you aren't pounding that input as hard when the ecu blocks the path of those coils.

 

I'll see how much work this will be tomorrow. I'll take pictures so everyone can see what to expect.

 

Figured it out. It's the top row 2nd wire under the black cover. Probably purple or pink wire. I'll cut near where all the wires come together.

 

this should help
