Enoch,
As seen, i do not supply supply the connectors... Purely because you can't buy new sierra connectors, so you will still need to strip your sierra loom of connectors...
It has the wires for the hazard built in and i can supply the flasher relay if needed
In regards to plug and play, You will need to lay the loom in the car and do it one wire at a time, work out where it goes... Cut it to exact length... Crimp it... Connector and attach to piece of equipment
If you have any queries, do not hesitate to email

Am going away of the christmas period but should still be in email contact
Thanks
Ed
