Thanks for the explanations RTB. I'll save those off for future ref.
I was making some assumptions but wanted to check before I did something stupid.
I have a break in the Y42 circuit and was unsure what the connections 24 & 20 meant. RTB's explanation is that they are just sharing a junction block. I'm not sure why the wire would change from 20 gauge to 18 but I don't suppose it's crucial.
Anyone know where Connectors C103, C106 & C107 live ? I fear they may be somewhere behind the dashboard.
If I can't find them I was planning to put in a new wire and splice into pin 76 at the ECM and pin 2 of the solenoid.
I've had to do this twice before with the R/F brake sensor and the horn circuit. It was a lot easier than pulling the dash out.
Thanks for the help.
