Connection for home made electronics shift lights

[JetspeedCamry]

I have an electronics shift light kit installed in my car, which is from the local electronics store.
It uses three lamps to stage the RPM's at what you preset. Ive got two of them running, one at 5000RPM(green) and the other at 6500RPM(red).

This kit offers various methods of connection to determine the RPM including:
-Hall Effect
-Points
-Low Voltage
-Signal Reluctor
-Ignition Coil

Several sources have said to me that my car uses hall effect pickup on the distributor, although, i havn't used any wires near the distributor, I have used a BLACK wire from the ignitor.

Problem is, it is very unreliable. Sometimes, both lights will come at idle, sometimes not at all, other times, the shift points are off. I want to trace the problem, so first I thought of asking where is the best place to have it connected to.

Thanks.

Bump!
Anyone?
88LE?

Bump again!

Not sure what the problem is, but the black wire on the ignitor is the tach signal.

And so is the negative coil wire, check connector on top of the distributor (not sure if 2VZ-FE has one, but 3S-FE does), and one of the wires to the gauge cluster.

Keep in mind that the engine revs faster then the tach. In other words if you stomp on the gas the tach might show 5,000, but the engine will be reving faster then that.

The problem is that it's giving a faulty signal atm. Sometimes it will work ok, sometimes not.
I just want to know where on my car is at least one of the points i described in the first post.

If i connect it to that point and it doesnt work, then i know its the circuit i built.
But i need to find out where one of these points are :
-Hall Effect
-Points
-Low Voltage
-Signal Reluctor
-Ignition Coil

Thanx.
