Hello,
I was thinking of adding a kill switch by interrupting the power between the computer and the fuel pump relay, which I believe is a dark green and white stripe wire. This dark green and white stripe wire is one of five wires going to the fuel pump relay, correct if I am wrong please:
1. Red : fuel pump prime
2. Grey: to the sender, powers pump
3. Orange: fuel pump/oil pressure switch
4. Dark green/white: fuel pump relay control from vehicle control module
5. Black and white stripe: ground
To splice into the dark green and white stripe wire,, the underhood fuse box needs to be opened to access the wires underneath, unless there is another way to do this without disrupting the box?
Alternatively, there is a grey wire from the fuel pump relay that goes to the fuel pump and runs along the frame on the drivers side. One can potentially splice into this grey wire. Unsure if it's "better" to disrupt the computer to the relay signal (dark green and white stripe wire) or the relay signal to the fuel pump (grey wire)?
Does anyone recommend using another kill switch idea that does not involve the underhood fuse panel and instead, uses the interior fuse panel to the left of the steering wheel or other wires under or within the dash?
Any ideas or feedback is welcome. Thanks.
