    Where is a good location to tap an accessory wire in the engine bay?

    Hi Everyone,

    Just trying to install a Dual Battery to the engine bay of my Petrol 120.

    Does anyone know of any easy to find accessory wires located in the engine bay, and possibly what colour would the wire be? I think it may be green but not sure? I do have a multimeter so can check.

    I did a search and a few people have mentioned tapping the windscreen wiper motor but as far as i can see that wire and the motor is hidden away.

    Any help is appreciated.

    Cheers.

    I had a spare relay spot not being used in my fuse box inside the engine bay that would only supply power when the IGN was on. You could check the same on yours. I needed power for a 5w LED otherwise if I need more current I would have use the power source to power a high current rely and getting power from the battery.

    See the following link. Mine is a diesel so your fuse box maybe different.

    Why do you need an accessory wire for the dual battery set-up?

    Thanks Winniliss! saved me heaps of time trying to dig around finding one.

    Bushbasher - I actually have a Thumper Dual Batt System. The accessory wire is needed to isolate the thumper from the main battery when the car is not turned on.
