It was Plug and Play. No wires splicing/cutting. Simply replaced the meter and inserted the the grip. After the engine was cranked up, the airbag and engine check light remained on which became a slight concern. So, just removed the battery terminals for 5 minutes, fitted them again and viola, no issues at all. It was a sheer joy to have this meter installed without any hassle.
Like I said, this meter is available easily for Prosmatec. I had to wait a little for the Manual one.
