My X is just over 10 years old but only has 55K miles on it. That's great, however, it looks like my second knock sensor is already failing. No SES light, but I noticed the truck was a bit sluggish so I hooked up the scan tool and sure enough, its a bad knock sensor.

It certainly seems cheaper and easier to do the bypass but with the SC, i wonder if i should do the relocate. Any input on this would be welcome, especially if anyone can point me to some good pictures of the harness. It seems that most of the linked images are no longer on the inter web.

Thanks in Advance! Rob

Relocate for the speed sensor, never heard of that. I have heard of a relocate for the knock sensor which is important for your SC X.

Bypass the boost control solenoid, it is activated when the knock sensor detects pinging.
I have replaced my knock sensor and done the knock sensor bypass (resistor mod) and bypassing the solenoid is the only long term solution.
I have 2002 SE SC and have owned it from new.
2 years into bypassing the solenoid and installing a smaller pulley and everything is fine.
