Please Help! Speed Pulse Wire To E.c.m. ??

[mark morris]

Hi, everyone I am installing a G.P.S. navigator in my R33 GTR. And need to find the speed pulse wire from the speed sensor to the ecm, to splice into so the unit knows how fast im traveling.

Just wondering if any one has done this before? and if they could give me any pointers to which wire it is.

Also the unit has two wires that need to go to the negative poles on the left and right speakers.? Just wondering, cos I have an amp wired up to them would too much power go through the unit?

CHEERS!, Mark.

what exactly are you trying to do. for speed grab the APEXi RSM manual and look up you your ECU. ( I have another way of doing it but explaining it over the net isn't that easy.)

what unit is this?

[raz0r$harP.UK]

speed sensor is wire 53 coming off the ECU

Rasorsharp , so is no 53 off the ecm the pulse, power or ground wire to the ecm?

Chris, what do mean apexi rsm manual, I only have a stock gtr computer? dose your other way involve a continuity check from speed sensor to ecm? cos I tried that.

The unit im trying to install is a PIONEER AVG-VDP1 vehicle dynamics processor it conects into the AVH-p5750DVD in dash dvd screen. has: GPS, SPEAKER LEVEL INPUT, G SRENSOR, GYROSCOPE SENSOR, RGB OUTPUT?

Any one here fitted one of these?

Off the service manual for the R33, it states that pin 53 is the 'vehicle speed sensor.'

Not really sure what you need as I don't have an RSM, but it has a 2-pulse speedo.

fitted way too many of them.

if you have the wire then the rest is easy.
