There are two wires that connect to the coil, one is battery voltage, you connect to the other. Some meters need an additional part to 1/2 the signal, as stock fires all coils at all spark requests, thereby doubling the reading.

If the LED fuel gauge does not have connectors to match the factory connectors, then you need to take this to a qualified tech or return the product. See the diagram for connection points. "Brand X" electrical products are challenging to install.

According to most posts the pink wire directly connected to ECM would be the TACH relay to AutoMeter Tach Gauge. 2001 FLHR can anyone reassure me on this one? Thanks inadvance

Kind of hard to see in the above wiring diagram, but the OPTIONAL tach is a PINK wire that goes to an 8 pin connector.
Pin #3 is where it connects.

From there is goes to the ignition harness, if a carb model.
-OR- to the ECM harness if a FI model.

Gmc problems

If you replaced the cluster, the tach was replaced. So its probably not a problem with both the old and new tach. Its probably a problem in the wiring to the tach. Put a multimeter across the tach signal wires on AC setting, rev the car, does the meter reading change?

Remote start python 533 attempts to start the car, shuts off, then on a again, does it 3 times, then stops

There are three possibilities for the situation you are describing especially if the vehicle has been cold for a while. The first possible cause occurs when the smart tach feature is used. In this case, the 533 is not receiving the proper signal from the vehicle that shows the engine is running. The remedy for this problem is to connect the tach wire from the 533 a proper tach source. The other two causes occur when the smart tach feature is not used and the tach wire is connected. If the tach wire is not connected to a good source for the tach signal in which case the wiring will need to be corrected. Otherwise, the tach signal will need to be relearned.

Put an rs82 bulldog remote starter in my 2005 town and country, and after 11 seconds it stops and re engages the remote starter and stops after 11 seconds and stops completely

It sounds like the RS82 is not getting a proper tach signal. If you are using tachless mode, the 12 volt constants may not be providing the desired signal. Recheck your connections to ensure that they are solid. The high amperage wires should be soldered. You will need to connect the tach wire if the connections are good. The tach wire can be connected to the negative side of the ignition coil's blue/brown wire or the blue/green wire at the PCM or you can use any one of the uncommon colored wire at a fuel injector.

I have an 89camaro irocz 28 with 5.0, with a rebuilt tranny about 3 yes ago. While driving on overdrive at about 40-50 mph it will shift into od geer then back to 3rd then od again what could be causing...

Yes it can be what it is doing is called hunting, As for your RPM tach it has nothing to do with it, Now your transmission is a 4L60 and YES it does need a tach signal or the RPM signal it doesnt matter if your Tach gauge doest work but it need the tach signal for the transmission to work. And NO there is NO VSS it needs TACH. or it will hunt for a shift that is why its doing this.Youll need to restor the TACH to the transmission so it can shift properly, Now youll either have a 4pin connection,1 wire or youll have a 4 pin 2 wire connection or youll have a 4 pin 3 wire connection This transmission need tach signal so bear with me i am going to some how draw it pretend your looking at the switch. connection

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
