can anyone tell me what wire to hook the tach pulse wire from the vdo xtreme to cant find one that works any help would be great
Do you have right dip-setting? Does it act like it shows rpm for few seconds and then drops?

yes but i am using all autometer and dont have a factory harness is there any other wire i can hook into and all the tach does is go to 6500 when you turn it on and cant get it to do anything
SO it will go to 6500 even if engine is not running? Do you have instructions? If it goes to 6500 and stays there i think it's expecting you to set second shift rpm for light... What does the numeric display says?

You must have dipswitches set to 1,2,3 on and 4 off or vice versa as there are some VDO's out there that had the ON/OFF marked incorrectly so it may need to be 1,2,3 off and 4 on as well. The yellow/black wire is the wire to hook into on a SRX.
