I'm trying to wire up my CRX to get the GSR motor I swapped in it to work and im looking at the chassis harness because it seems to have been messed with and I'm seeing this orange plug. Is this from a previous alarm install? Could this be part of the problem I am having getting the car running? Thanks

 

That looks like a stock "jumper" plug.

Are you getting spark?
Are you getting fuel? 94
