Parts lookup and repair parts diagrams for outdoor equipment like Toro mowers, Cub Cadet tractors, Husqvarna chainsaws, Echo trimmers, Briggs engines, etc.
And you won't find the older number as Briggs has removed it. Read the part note for item 125. It basically telling you to use item 125A. Same on the PowerPortal IPL.
And it can be either one of the superseded PNs listed.
It sorta like looking for a wiring diagram for a CC 17RRCACS010. Late this afternoon my part supplier unknowingly gave me a hint how to find it and with 30 minutes after getting the phone I had found it. Just had to do some cross referencing to find it. Now I can convert the harness brought me for his mower and won't have to wait 7-9 weeks if not longer.
