remote starter toyota rav4 2003

HI EVERYONE I think the easiest approach to tach wire is the data link just below the fuse box on rav4 2003. The tach signal is the pin#9 which is the bottom row, pin#9 is most left hand side of the connector and to test it is to connect ac voltmeter with black to ground and red to pin#9. Am I right?. What are the alternatives. Thanks a lot

Correct, black wire at pin 9 according to Directwire, test as you've stated with your DMM set to ACV, should get 2-4VAC at idle increasing to about 5 on revving up. N.B. also on some Toyota/Lexus, black wire with silver dots at OBD ll socket if this is easier to get at. Or is you're data link my OBD ll?

HI Howie

what is the difference between wire with dots and stripe. I am not clear about it for example say black wire with red stripe colour  is marked as BLACK/ red now what happens if black wire with red dots.

Thanks a lot  Mike

It should be obvious, stripe is the second colour running all the way along, dots are at intervals. The BLACK/ red you mentioned (which just happens to be another tach location in the engine bay on certain Toyotas) means black primary or major colour, red secondary. If you look down at the wire side of your OBD ll or data connection, it's over to the right, pin 9, i.e. top right same position and colour as late BMWs, unfortunately out of those 16 pins, only 4 or 5 are industry mandated, CAN hi lo etc. The rest are up to individual manufacturers.

HI EVERYONE Regarding tach signal on RAV4 pin#9, I get 7.8 ac volts even when gas pedal pushed for higher rev but no considerable voltage change. It is supposed to be between 1 to 3v ac. I wonder anybody have any idea. Thanks a lot Mike

Run your tach lead to that wire without cutting short or soldering, finish installation and see if you can successfully programme tach, if so, cut to length and solder etc.

HI EVERONE Thanking you all for all your help and input. Remote starter working ok. Mike
