Hi Greg,

That's probably me that you are thinking about for the wiring

pin connector for the EC3 instead of a 37 pin connector for the EC2.

If you go to my site at http://roblinstores.com/ and fill out the
lengths you need for the 13B cable, you can get a pretty good idea of
the cost. =A0Put in double the length you need for injector and coil
leads for the individual lead option. =A0That will give a pretty good
estimate.

Let me know if I can be of any further assistance.
