Raptor install question
I have the red wire ran to a switched power source, black wire ran to a ground under the dash and the green wire ran up to the lower pcm harness or one farthest away from firewall connected to the white wire coming out of pin #10. The shift light blinks back all the correct sequences for my selection just no light at the desired rpm? From everything ive read I would think I have it hooked up properly. I have it set on 4 cyl mode which is 1-down 2-up 3-down on the dip switches and have the rpm selection at 2500 rpm just to test and im not getting anything when im at that rpm.
I thought maybe at first that the original scotchlock wasnt doing the job so I ran the new green wire from the raptor and soldered it into the tach line and still nothing. Please help

Would it be possible that my 2000 has a pcm out of another year? I noticed on harlans website that 1998 is different than 99-00 but didnt say anything about 2001-2002. To me if i cut the tach signal wire I wouldnt be getting a reading on the factory tach, am I right?
