Simply not true - you can ALWAYS run a relay - and you ALWAYS should.
TRS sells great relay harnesses - with any specific connectors you may need.
Obscuring that sensor is not the answer.

There really is no 'special' way - the harness is either correct and it works, or it's the wrong harness or defective. Or the heads themselves are wired in a non-standard / kludged fashion. Pics of everything would help.
Running without relay isolation and independent fusing is asking for trouble - especially on a truck with a SJB ( Smart Junction Box).
All of the fellers on here with your era of truck running proper high quality retrofits (not PnP garbage) are using a quality harness and have zero problems.
