Has anyone got feedback on the American Autowire harness 510089 into a Blazer.

My understanding is they are for SWB truck so are a little longer.

Is there a better option.

My planned electrical upgrades are Holley Terminator fuel injection, with in tank fuel pump. Thermo fan, headlight upgrade, stereo, possibly E-Stopp park brake.
