Adding Viper keyless entry
 

Hi all.

I had a quick question. I just purchased a Viper 211HV keyless system for my 07 Mazda3. I installed all factory power locks and windows last year.

When I'm installing the new keyless system, do I splice the lock/unlock wires into the existing wires going to the passenger junction box? Or do I cut them and connect them directly to the keyless entry module? I figure if I have to cut them completely from the PJB, I'll lose the functionality of the central lock feature on the driver's door key lock, but it wouldn't be a big deal because I'd now have keyless entry. Thanks in advance.

I didn't think they sold any with no power anything...

It would probably be easiest to get the schematic for the electrical system to see how it's put together.
But if it's all from scratch, there is probably an input on your new RKE system for a manual lock / unlock button, so you should be able to wire it in.
