				testing wiring harness
			 
			
			Is there a simply way to test the engine wiring harness?  I have mine out ('88 3.2) for the rebuild and don't want to spend nearly $900(!) just to replace it if it works fine.  I have been careful to avoid bending it but I'd like to know if it's working properly before I put it back in.  FWIW, it apparently was working fine when I removed it.  I did a search and it appears these can be rembuilt, so to speak...is this a DIY project?  I'm fine with mechanicals but electronics are a bit of a mystery.  Would I just test continuity or should I check resistance?  That's probably the extent of my abilities, electrically speaking.

			When you test a harness, it's mainly continuity you check.  If you use a typical multimeter, you'll see the resistance anyway.  A physical inspection of the harness and connectors (looking for damaged insulation/wrapping, corrosion, bent pins, etc.) is also useful.  Get a meter and read the instruction book.  It's pretty basic.
