Stupid Question about Radio/Headunit swaps

I have a Becker headunit sitting around from a project I never went forward with (who needs a radio in a TR with full Tubi?)...I wanted to swap it in for the OEM Honda unit in my (also new to me) 98 Honda prelude. I plan to use the factory amp/speakers/etc.

I know I need a harness adapter (Becker/Blaupunkt <> OEM 98 Honda Prelude harness).

Where can I buy one of these pre-fabed?

Yes I can sit and make it buying each half and doing a lot of splicing, but at this point its just faster/less headache to buy it.

 

Ha! Figured it out.

The Euro Standard is called ISO (one of those things I once knew but have since forgotten).

I just found a factory <> ISO harness and that's it. Ironically the cost of the complete unit was less then the individual halves!
