I have a 1996 cav 2.2OHV 5 speed, and I just installed a sunpro tachometer in my dash, now the car did not have an original tach to feed the signal wire from so I went under the car and aimed for the coil pack.
Now I checked the haynes manual, but it shows a new coil pack in the picture with only 1 signal wire, but upon inspection, we found a total of 2 connectors and 4 wires.
Connector 1 had a black and red wire, obviously ground and power wires?
Connector 2 had Orange and White Wires, which I thought were of course the signal wires.
I spliced the orange wire and ran the tach signal to it, it works but isnt reading correctly.
When the engine is audibly to 6 thousand rpms (were assuming from listening to exhaust note), the tachometer is only reading 1.5k rpms, and its showing that the engine is idling at like 200-300 rpms?
What could be causing this?
To lengthy of a signal wire?
Were running the tach to the wrong wire?
Thanks
I'm not 100% on why your getting that, but I do know some tachs are set-up for V8's, or V6's and have to be modified to work on a 4 cyl. Usually by clipping a wire. When I got my shift light it had a switch for 4-6-8. This could be part of your problem. Also I think on 96 there is a tach slot in the fuse box under the hood. Look, if it is then you can get your tach signal there.

thanks uhh the tach dosent have that switch thing there are just four wires sticking out of it, ground, two positives (one for the light), and the signal wire. And about the fuse box i think there is a slot in there but im not sure. If there is would it really be that easily to install? I mean have you heard of anyone else installing it like that?
On the tach, there should be a switch for 4,6,or 8 cyl. You may have to remove the back panel on the tach, but there is a switch there. Aswell, I think you need a tach adapter because your motor has two coils, and if it's hooked up to one coil, it will not get the correct signal.
