I have just fitted some third-party rear LED lights to my 7 and terminated the wires with Econoseal connectors to match those of the OEM lights.
It’s been a while since I fitted any of these connectors so I had to “relearn” how to!
Initially I wrote this as an aide memoir of what I had forgotten last time (and would probably again!) but thought it might be a useful guide for anyone doing this for a first time (how can this become a Technical Guide?)
I use a specialised Econoseal crimp tool like this one and also sourced the connectors from Polevolt.
The Econoseal connector consists of four parts - wire seal, connector pin, connector body and yellow seal.
This is what you do…
put any necessary grommets on cable
strip cable outer so ~25-40mm of wire shows
put wire seals on wires - wider bit on first
strip ~4mm of insulation from each wire
move wire seal up so it is by the end of the insulation
squeeze outer tangs of connector pin so roughly parallel, this enables it to sit in the tool better
put connector pin into crimp tool - the tangs should be within the tool and connector pin emerging to the right
squeeze crimp tool so connector pin is just held
holding crimp tool in right hand, insert wire so small diameter bit of wire seal is within the connector pin (no photo as I only have two hands!)
squeeze tool until ratchet releases
connector pin’s tangs should neatly grip the wire seal and the uninsulated bit of wire
insert the connector pin into connector body with the crimped bit away from the lumpy bit on the connector body (or with the plain bit facing the lumpy bit if you prefer)
the connector pin should click softly in place with the wire seal sealing the back of connector
might need some minor fettling so connector pins align
insert yellow seal bit so it clicks in place (no photo! 🤦🏻♂️)
sorted - job’s a good un!
