While we don't have a 4-way connector that has 8 wires total that run to it you can use the Wesbar Wishbone connector part # 002402 which has two wires ran for the running light circuit. You'd just need to match up the remaining circuits to this harness by running the two wires to the single wire on the connector's wiring.
