Re: Lift pump Reply #25 – December 07, 2021, 10:30:05 am I disconnected the green and black wire coming out of King Cruise box that I connected yesterday and now the retarder works. I think the fan was a non issue. Quiet possible the extra ground I installed on the cruise unit yesterday solved the throttle issue. Drove it to Texarkana this morning putting 75 miles total and everything works as it should. Had a lot of help from jor as it seems he learned quiet a lot about king Cruise in his trouble shooting history and shared with me. Quote Selected 8 Likes
