I'm tuning an LLY and putting in a DSP5. The pins I need to tap are 32 and 50, in the tutorial it says to take the pin fillers out. But on my LLY there are wires coming from pins 32 and 50. What should I do?

Thanks

Either you have the wrong plug, or someone has previously wired some aftermarket devise into the truck. I'd double check the plugs, and the pins you've selected.

Ah ok, I think I have the wrong plug then. I took off the first one, and thats the one I was going with. Ill try the last one then. Thanks!

look at the colors in the tutorial and match them to the colors on the inside part of the connector.

The tutorials can be a bit deceiving if you're not careful, it looks like you're supposed to grab the blue connector if you glance over page 17.. but that's for the DSP relay only. Need the gray one for DSP5 install. I know you already found this out Sal ;), but for the next guy who searches and finds this thread....
