I don't think anyone has found a source other than the Ebay link.

Later in the day I decided to replace my steering wheel and I got to use the switch

Longacre Racing Products sells the battery switch, it comes with a mounting plate and makes for a better install then this shipping switch.

Oh great - I just bought another one of the hella brand for my other car. Looking through their site I only found this - $37-ish

Other than that ^ they only have the basic switch. no kit. They also sell wiring but for $99 :wow:

if you could find the item that maybe has a longer wire that would be great.

These are available for $13 and $33.

I saw those but its not a kit. I may be overthinking this but since our X like most BMWs are sensitive to voltage changes the wires have to be properly soldered and not just crimped since this will be the main ground line.

ebay has a lot of turn switches but no cables. Found a seller that has this but he has blocked any communication regarding his item. I wanted to know how long is the single wire with the battery terminal and ground connector

battery switch - JEGS High Performance

Jegs has a wide choice of switches. They have what could be called kit but they start close to $150.

yikes. for the $120 difference I will just have to put up with moving the sub box and lifting the cover everytime

No kit needed, the switches I showed in post #45 can be installed right in the positive cable off the battery with no issues.

I can't seem to find the ebay link posted, I thought it was. Sorry, if this is duplication. I just ordered one--it says there are only 13 left, 12 now.
