Thunderbolt IV Module

I just purchased a new thunderbolt IV module b/c I am converting from the thunderbolt V setup. Built a new motor and want the set advance curve.

My problem is I purchased just the module and it did not come with a wiring harness. Was wondering if anyone had a spare harness that I could purchase?

I wasn't aware you set the advance curve with those. I always thought the trick was, to get a V-6 module. They only have 14 degrees of advance. But this could be old school.

I think what he is saying is that a TB IV has a fixed curve based on rpm. The TB V curve varies depending on kniock sensor readings.

Like Griff said, the TB4 has a fixed curve. Not sure about the 5. The V-6, 14 degree modules throw in all the advance pretty early which could be good or bad depending on the application.
