So, I've upgraded my old broken 2G to a nice 3G unit from a 97 V6. I've had no troubles with the install, and everything works great (I should have done this ages ago!) My question is with grounding for the new unit. It's not been necessary yet, since there's not currently too much demand for power in my car, but I was wondering if anyone knows a good location for an additional b-to-chassis ground. The Negative battery cable ground seemed like a good spot, but I thought it might be redundant. I planned on running it to the dedicated computer ground next to the starter solenoid. Any input would be appreciated!

Upgrade the existing block to chassis ground, vs adding a second. That way you avoid what is called "ground loop"

Makes sense, thanks! That would primarily be the one from the firewall to one of the trans bolts, correct?

For best results use a bolt to the back of the head.
