That is true, just installed the clifford matrix one mile range remote starter system... while looking at the pcm, it will be the harness farthest to the right. yes there are 2 black wires but the correct one is the left of the 2 on the very far right harness... verify with a volt meter... hook up positive lead to constant + 12 volt source and probe the ground to that black wire and start the engine... meter will read between 1-6 volts... good luck.

Is there any chance way to check the camshaft position sensor on a 2001 Hyundai sonata?


The connector for cam sensor shows three wires, that should be ref voltage-pink wire, black with white tracer- ground, signal-black wire. The signal wire carries signal to pcm. To check signal, is you have a digital multimeter that has a tach--duty cycle or dwell setting, they should react to a pulse on the signal wire. The ref voltage is 12 volts, probably goes hot with key on. The black wire with white-ground use an led testlight to check ground, should be computer safe.

There are several circuit that use the same 12 volt reference.

Which crankshaft sensor drives the tach on 2003 Malibu


It is above and behind the Alternator on the top. It looks like a "D" battery standing-up with a female pigtail hook-up on the top of it.

What wire could I splice into on my 1996 Toyota Corolla so that my Tach can read the RPM's from?


If the tach was an option for your corolla, it is very likely that the wiring harness in your car would have the connector for the tach. They would use the same wiring harness to cut costs, and whatever is not used would be left open on a car without a tach. You will have to find a wiring diagram to check for the tach connector-it would be up under the dash leading to the cluster. In earlier days, tachs were connected to the coil's negative side of the primary circuit.

I have 1993 dodge dakota 3.9l v-6 with trouble codes 12,15 and 55 what do they mean


the trouble codes are as follows code 12 problem with battery connection. direct battery input tp pcm disconnected within the last 50 ignition key-on cycles. code 15 a problem with the vehicle distance/speed signal. no distance/speed sensor signal detected during road load conditions. code 55 completion of fault code display on check engine light. this is an end of message code. the speed sensor is located on the transmission/transfer case extension housing. check plug connection to speed sensor for power using an volt meter. connect the positive side of volt meter to the orange wire terminal and the negative side of volt meter to the black/light blue terminal. the voltage should be approximately 8.0 volts and to check the voltage from the pcm connect the positive end of volt meter to the white/orange wire terminal and the negative side ti the black/light blue wire terminal. signal voltage should be 5.0 volts. if there is no signal voltage signal, have the pcm checked out. if you have both signals from the terminals then remove the vehicle speed sensor and check the speedometer pinion for worn or missing teeth.

I need to know where to wire the green wire to read RPM's for an aftermarket tachometer install on a 1999 chevy s10 with a 2.2l 4cyl.


It is usually to the positive side of the coil - also depends on what type of distributor cap you have, if there is a 3-4 wire plug that goes to the cap, one of them should be marked TACH

Defective tachometer and speedometer


Do the following:1)key in the ON position:remove the 7.5 gauge fuse.Tach needle should read "0:". 2)put it back,go on the engine and unplug the green plug on the igniter -the big one,with 5 or 6 wires on it.The needle on tach reading should be zero.If not you have a short circuit on the black wire between that plug and the plug on the conbination meter.3) If the reading is zero with the plug disconnected,the black wire for the tach is short-circuited inside the igniter. I have one available.email daddykouki@gmail.com
