stevebo-(Moderator) 8,034 #1 Posted April 4, 2009 I am looking for a wiring diagram for a 88 520HC. I bought it and will be putting an Onan 16 in it. I am looking for the diagram that goes from the square plug to the harness on the motor. I assume the 16 and 20 use the same harness. Any help would be great. I was able to look on partstree but it is not color coded and this type of work is NOT my strongpoint. Thanks- Steve Bo Share this post Link to post Share on other sites
Buzz 502 #2 Posted April 4, 2009 Steve you can download the 523 pg Electricial demystification Guide from Toro and that has your wiring diagram. It starts on page 7-119. Go to: https://lookup3.toro.com/request/request.cfm Enter your model number as C1-20oe01 and put "none" for serial number. Have fun......... Share this post Link to post Share on other sites
