Wiring Advice Needed!

Hi Folks,

So I started fitting the electric window regulators to my Golf last night. Tonight I'm going to build a loom for the system, but just wanted to check something before I start... The OEM wiring has a 30amp fuse shown for the system, which I will be using too. So should I also be using 30amp rated wire and spade connectors etc.? Or can I get away with using a smaller fuse and lower amperage wire and terminals?

I'm only trying to avoid the ball ache of driving to the shops

Cheers,
Josh

Nah...

I'm guessing the fuse is for all 4 windows - so the wiring to each regulator should be rated at 7.5 amps minimum (30/4).

Cool, so 30amp cable for the fuse and then onto the relay, then after the relay where I'll take a feed for each switch I should be ok with 10amp per switch?

Used an inline 15 amp fuse I had lying around in the end as I'm only installing power windows in the front. I put the inline fuse between the permanent live on the fuse box and terminal 87 on the relay. I then ran 2 lengths of 8 amp wire to the switches, and then to the regulators and back. Then earthed each switch with more 8 amp cable.

Job done

Sounds good to me
