stevebo-(Moderator) 8,333 #1 Posted June 10, 2015 Are the wiring harnesses on the engines of a 520-8 the same as a 520H? I might want to do a drect swap. Share this post Link to post Share on other sites

cleat 6,100 #5 Posted February 13 I believe the harness is the same, just an unused wire or two that would go to warning light sensors. Even the 520HC engine I can plug into a 520H. I even plugged a 416 engine into a 520 with no issues. 1 Share this post Link to post Share on other sites
