1. This is how I wired it up with one mistake I noticed just tonight. I had H2/24 on the 24 pin connector of the viper going to pin 3 of 12 pin connector on dball2. I need to fix this like I have it listed above.
2. Right now the remote start will not work. Door locks work fine. Do you see anything that could be the cause of no remote start? I did get it to remote start once by turning the ignition to run and then pushing remote start button, but it would not shut off with remote.
3. Do I need to wire in a relay for the 2nd accessory brown wire near ignition harness?
4. My alternator is currently not charging. Could the brown 2nd accessory wire not being connected be the problem?
5. I have programmed it for automatic transmission, and to use the wait to start light as I have it wired that way.
I am a total rookie at this! If you have questions on what I wrote here please ask and I will do my best to clarify. Thanks in advance.
