How may people have wired an EC2?
How many people need to wire an EC2?
How many people have wired it more than once?

I have an EC3 that I wired to a 20B on a test stand.
I haven't been able to get the engine started.
The EC3 is currently in Tracy's hands while he inspects if for possible
damage, possibly from inadequate or faulty ground.

I notice there are two connectors instead of one. I assume
the small one goes to the coils and injectors.

Is that right? Can you scan the wiring diagram and upload
it to me?

Paul Lamar

I don't have a scanner Paul. It's a little dated but the PDF manual from
Tracy's web site might be of use.

That is the EC2. I have that one.

Paul,

Here are 3 schematics from the EC3 Setup and Installation Guide.
 They are sent as three separate zipped pdf files.

Thank you very very much William. That is a huge improvement.
The same number of wires are used in the EC to PCM connection so I will
order some color coded cable for that harness and sell it by the
foot.

When working on well sites, the sparky's used a couple of cables that could be
of use. One is Belden cable. It is similar to the RS232 cable. Another was for
higher current apps. It has a black or tan outer sheath with 8 pairs of wire
inside. They are not color coded, but numbered 1 to 8. They have a gold color
foil around each pair. Easy even for a burnt out old mechanic to keep
straight. If interested I will find out the name and source of the second cable.

Not enough wires. I need at least 11.
