FT-DM600

Compustar FT-DM600 Door Lock Harness with Polarity Adapter

This is the Compustar FT-DM600 Door Lock Harness with Polarity Inverter (flips polarity from negative output to positive output). 

This product serves two great purposes:

1. Easier to install than standard relays, if all you need to do is flip polarity from the default negative output (on all Compustar products), to a low current positive trigger. This is becoming rarer and rarer today, now that most vehicles require an interface module, however there are still vehicles that have positive trigger door lock circuits that this product can assist with.

2. This product comes with the elusive Compustar door lock harness that they (Compustar) does NOT include with their products. Meaning, you can use this to unlock the other POC (programmable outputs) that you were originally using as your lock outputs, not only that, but this harness provides you with the priority unlock output you may need as well! Simply cut off the polarity inverter, and now you have the harness. 

We have no idea why they (Compustar) do not sell just the door lock harness on it's own, but this is the next best thing.
