2280 Xr Pro Ultrastart

Hi im installing a 2280 xr ultrastart with an idatalink bypass. I have one question i have two 4 pin connectors. Not sure which . Anyone know? Thanks.No better feeling then getting a remote start to work right!

Here is a link to the 80 Series Install Guide : http://www.ultrastarters.com/manuals/MAN-80s-INSTALL-2011.7.22.pdf On the Page 4 diagram, it looks like you would use port marked "BYPASS MODULE DATA COMMUNICATION PORT" at the bottom. Not sure if it is 2-Way capable. Might be one-way only where the 2280 can send commands like Lock and Unlock but does not receive inputs like Brake, Tach, Door Status, etc. I never tried anything 2-way with them.Soldering is fun!

Thanks Kreg, I hardwired it anyway I was Just Curious to see if the 2 or 1 way communication would work. Ill just stick to hardwired.No better feeling then getting a remote start to work right!
