I am going to install an aftermarket alarm/remote start in my 05 xA. I have in the past on other vehicles used a "turbo timer harness" for alarm install so I can leave the factory ignition harness intact.

Does anyone know if there are any turbo timer harness' on the market that are compatible with a Scion xA?

 

Looks like the HKS TT-8 harness (4103-RT008 ) may fit the xA. This harness is used on the Vitz/Yaris. I wasn't able to find one in the USA, and unwilling to pay international shipping for it so I'll wire it up the old fashioned way.
