I ordered a new under valve cover wiring harness from RiffRaff. How easy is this to replace? I couldn't find any step by step instructions for it. Will I have to remove more after I remove the valve cover? Any advice is greatly appriciated.

 

Just remove Valve cover, disconnect all the UVCH connections (Injectors and Glowplugs) then swap out the harnesses

It really isn't that big of a deal.
I'm still trying to figure out my issue. Good luck

 

Its simple once you have the valve cover off, basically you have 4 injectors and 4 glow plugs. Each injector gets a plastic plug with the metal clip. And each glow plug gets the female plug, I believe it is white. Hook up the injectors first, I think it is easier. Then use a pair of needle nose to hook up the glow plug wire, helps to push it on to the plug. A good head lamp will help you see everything more clear.

Good luck man

 

Clean everything the connectors on the VD gasket with electrical cleaner and really inspect it closely. You don't want what happened in the picture below.
