Paul,
In the installation instructions of Tracy's EC2, he mentions that you

will need to buy a SPDT automotive accessory relay (10 amp or higher) for
injector staging control.  He also states that these are available at most
auto parts stores, but when I asked for this at several local parts shops
nobody knew what to give me.  They wanted to know what vehicle make and
model and what it is used for in the car.  Can you give me any tips on what
exactly to ask for?

And by the way, if anyone needs to buy those expensive little GM coils

and connectors they can go to the following website:
http://www.rockauto.com/

Coils -    GM part# 12558948  or  AC Delco part# D580    $ 31.90 ea.
Connectors -     GM part# 12102741  or  AC Delco part# PT368    $ 15.29

ea.

Thanks,
Don Mitchell

The staging relay is only used on the 20B version.  I now stock the relay so
contact me direct if you 20B EC2 users out there need them.
