Blue Bird No Start / Safety Interlock

After doing all the things I read about with the interlock no start safety system, cut wire-start, cut wire-start, cut wire-start, I did really well, yesterday. Went out this morning and it wouldn't start. I know I'm not the first guy to have this same problem. Research, research, research - no answer to my problem. I did find one good hint to bypass the whole system, but not the actual answer.


1999 BLUE BIRD TC RE. Can't vouch for any other year, but for the '99 here you go.

Behind the drivers wiper door is a panel housing 10 relays and the flasher for the turn signals. What I read from PNW-Steve was info he received from a Blue Bird technician. Find the VanderLock relay and remove it. Jumper pin 30 and 87a. Problem solved. My problem is, there is no map telling me what relays are what. I used the age old process of elimination. Standing in front, looking at the box, my relay was the bottom rely in the left column. Hopefully this will help someone else without pulling their hair out.
