MSD magnetic pickup tach adapters maintain accurate tachometer readings. If you are using the magnetic pickup input (green and violet wires) to trigger your MSD Ignition, you will need one of these tach adapters. These units will correct the operation of most voltage-triggered tachometers that do not work directly off of the tach output terminal of your MSD unit.

Installing an accurate aftermarket tachometer on diesel applications has been problematic, until now. AutoMeter diesel tach adapters are ideal for all vehicles equipped with an alternator needing an accurate tach signal. A small pick-up probe is strapped to the outside of the vehicle's alternator and inductively leads its rotation, thus requiring no drilling or modifications for installation. They're compatible with all standard-ignition AutoMeter tachometers and are warranty-friendly. With simple one-touch calibration and widespread uses, AutoMeter diesel tach adapters are just what you need. Additional features: * Generates a standard 12 V square wave tach signal for RPM devices * Discreet status light indicates operation

Holley tach input ignition adapters are only used on applications using a CD box, such as an MSD 6AL, while not using timing control. They plug into the connector labeled "ignition" on the main harness. The loose yellow/black lead connects to the "Tach Out" terminal of the ignition box. Never connect this wire directly to the ignition coil.

MSD tach signal GMR pickups simply attach, with no splicing or cutting, to a current-carrying wire, and turn that information into a 12 V rpm signal. That signal can then be used to activate a shift light, rpm activation switch, or tachometer.

MSD distributorless ignition tachometer adapters allow you to install an aftermarket tachometer on vehicles with no distributor and multiple coil packs. These compact tach drivers measure only 1.5"x 3.5"x 2" and are potted with a polyurethane compound for vibration and water protection so it can easily be mounted under the hood. It wires inline on the coils' 12 volt supply wire where it senses the current going through the wire and converts this information into a 12 volt output signal that most aftermarket tachometers use as a trigger signal. MSD distributorless ignition tachometer adapters can be used on 4, 6 or 8-cylinder engines.

If you are triggering an MSD Blaster, 5, 6, SCI, or 7 Series ignition with its white wire or points terminal, with a non-current limiting ignition (originally equipped with a ballast resistor) you will need one of these MSD factory ignition module tachometer adapters. They correct the operation of most voltage-triggered tachometers or fuel injection systems that do not work directly off of the tach output terminal of the MSD ignition unit.

CA offers tachometer filters for a variety of applications, including many Chevy Corvette models from the 1970s, '80s, and '90s. These devices remove leading or trailing pulse signal interference for tach RPM gauges, preventing aftermarket instruments from acting erratically. They're recommended for vehicles with poor quality engine RPM pulse signals, single coil ignition systems, and point-style coil ignition systems. Each replacement filter is manufactured from factory materials and specifications to ensure proper fitment and performance. They meet or exceed OEM quality.

Eliminate tach signal noise and surges caused by your ignition system with OER tachometer filters. These components are recommended for vehicles running a tachometer designed for points-style ignitions for a crisp and cleaner signal and install between the tachometer and the ignition trigger source. The tach filters are designed to trap, redirect, and dissipate the high-voltage spikes and surges that are emitted by any late model, high-energy ignition system. The filters also modify the sharp up and down spikes into a semi-square wave signal for steady readings and faster pointer response.

Longacre stepper motor tachometer filters prevent erratic gauge operation by filtering out dirty electrical interference from selected high-power ignition systems. Installing a tach filter will clean up the noisy/dirty signal and therefore smooth out the reading on the gauge.

Classic Instruments pull-up resistors are needed to enable their standard (non-ZST) tachometers work with your GM LS-Series engine. The pull-up resistor will boost the weak LS 4-cylinder signal to the tachometer to one it can recognize. Most stock ECM GM computers will require this part to function correctly with a standard tachometer.

If your tachometer is functioning erratically, one cause may be a defective filter. AutoMeter tachometer filters will improve the unpredictable operation by removing interference and correcting weak or spiky pulse signals caused by points or noisy ignitions. Fix your tachometer's signal surges with replacement filters from AutoMeter.
