I am currently upgrading the single electrics with a 12S kit and am wondering if anyone has experience of the second supply on a Tec3M switching relay. I am thinking that the second supply should be from an ignition switched live, whereas the first is permanent live.

If so where is the best place to take a feed from? On my Saab I found a fuse box in the boot, but that’s not the case with a T30.

Thanks in advance.

Is the cigar lighter in the load space right hand side not switched by the ignition?

Good thinking, I’m obviously getting too old to play these games.

Thanks I’ll be be doing the wiring tomorrow.

I found an easy route down the left side for the feeds, there is also a blanking grommet below the pollen filter which gives easy access to the battery.

No drilling or major work and you will probably do the whole wiring job in well under 1 hour

2.5mm flex cable and 15 amp fuse under the bonnet.
