part number question

[41motorguy]

Can someone help with a p/n for a harness to connect my 2006 f115txr to my multi function tach and what else would be needed to install a water temp gauge ? There is a 4 pos connecter by the main harness but cant seem to locate the harness . Just want to be sure the warnings are working .
