Hey guys, thanks SO much for the support and direction. I tried again today and what do you know, I was able to engage the 8mm torx head with a 1/4 extension for use with screw guns to hold the various tips (1/4). I was never able to disengage the clip. If anyone is gonna do this, I suggest an even longer extension or 2 together. Pulling the CPS was tricky, took some time rocking from side to side up and down. Removing the clip after removal, not a problem. The clip actual "clicked" when disengaged and engaged, so CF'ers talk to us (a little). I read a post on another site that suggested to tie a thread around the bolt head in case it gets dropped (I dropped it once and fished out with thread- a GREAT suggestion). I don't know how anyone can depress the locking clip closest to the wire plug and pull the plug at the same time- with one hand. I could not. Anyway, replacing the new CPS, was tricky too. There are 3 very slightly raised ridges on the cylindrical section that enters the engine block. It took around 4 times to get the CPS to line up with the receiving female threads in the engine. Once I got the CPS in far enough, I used a small ratchet to ratchet the bolt down, little by little- that took a while. Anyway, the CF fired up and now for the RCM repair. Thanks again to all who responded. The link below has great instruction and wonderful pictures for anyone to review. Also, a question: the removed CPS said Bosch on one side and Mercedes on the other side but the new Bosch only says Bosch on one side (no Mercedes). Is the removed CPS original?? Or did someone prior to me do this change? Thanks again!
