The Trekker may have a bunch of different stuff on it that a regular truck wouldn't have, in fact I'm almost certain it will have extra junk that a pickup won't have. Have you tried Winnebago for one?

i havent tried winnebago yet but it looks pretty basic. i think some one along the has put a 20r in there and cut the wires and only used what the needed to make run so im going to attempt to figure out which wires go were . I would like to put the 22r back in there so im keeping my eyes open for one

Might be a 22r/20r and instead of wiring the engine to match they did the reverse, which would just be stupid.

Try autozone.com. They have online Toy schematics.

I didn't even think of them, they actually do have an extensive site with install, troubleshooting, diagrams and the like.

Hey trekker, did you ever figure out what it said on the block?  I thought one of my blocks was a 20r cause it was in an 80, so I pulled the head to use on mine and noticed it was a 22r head, so I'm hoping the block is too.  I'm not sure cause the block tag is smooth and just has ATK stamped in it.  I'm hoping it's an atk 22r cause they're supposed to be pretty good engines.

i looked on the block and saw some numbers but nothing stating its a 20r if it is i want to change it hopefully to a 22re. i would like to put a 3rz but i think that would be to much money and wiring for me to do

Let me know if autozone doesn't work for you. I have a Haynes manual which has wiring diagrams which seem to be copies of the fsm ones.
