Holley adaptor harness

[GNVYUS 1]

Anything ever come of this? Holley HP with a plug and play harness would be great for those of us considering moving onto a different GM engine later on but want to max out the current combo.

GNVYUS, I just had the Holley HP Installed by Don Cruz. I used his custom made wiring harness which was a direct plug and play to the existing connections. I also bought his smart coil adapter which bolts to the valve covers. Pretty sweet set up!

Since I am a Holley dealer and sold it to a few Buick guys (with requests for a few more) I decided to get with Casper's Electronics about making Buick adaptor harnesses. These will be similar to the current XFI adaptors. Currently, there is a shortage of a certain connector, once they become available Casper's can start production.
