just run the wire from the box to the resistor and then to ground. It is just Tricking the box into not turning the warning light on. I was told that it used this input for changing timing for warmup but if it did, I found no evidence of it. I tested both ways.
To the answer on the pipes, in cuting and welding them, the older style gave more flexibility having the small ends. If I had both sets of pipes, I would use a combination. The outside lower one being adjustable would have given a better fit.
Make sure you put the srx air blocker on your foot well or your foot is going to burn up.
Too bad all my original stuff was lost on Riches site. I had alot of great testing info on these pipes, slp, jetting, tempaflow, air box temp testing. I will never post tech on others boards again without backing it up to my own computer.
