Stupid wiring questions

[Scottcooper85]

Couple of questions -

what amp cable should I use to run live from a boot mounted battery?

Which is the temp sensor wire on the back if the digi dash and if I tee into it for a gauge will it be okay or split the currant and make them both run low?

thanks scott

Well if it helps i used some 30mm2 cable on a c20xe corsa,think was rated at 200amps or so but again wi depend on what engine your running,its fairley expensive out of motor factors tho if you can find an e30 bmw in breakers will be handy take the cables junction box and battery box

An old jag late 90's has a long battery lead as the battery was in the boot, it's round posts and a crimped ring terminal that should bolt onto the starter. There is also handy connector posts down at the kick panels for safely extending the cables
