DIY help needed on Spark plug replacement
For those that have replaced their plugs (I'm running a Renntech ECU upgrade and have read that the newer OEM sparkplug are better) is there any trick to getting the electrical connector disconnected at the top of the igniter coil??
I release a grey lock at the top by sliding it out, but then it seems like the whole harness should just unplug, but I'm pulling relatively hard it it doesn't move? Trying to be careful not to break/crack the plastic connector.
Thx in advance,Will

Hope this helps. Some of the links for the Pics seem to be dead but the info is there.
Good Luck.
