The PO spliced a 1" piece of wire in the 16ga red with white tracer off that big factory splice from relayQ2.
That big 10ga wire off that same splice had about an 8" piece of wire spliced in, it had the what looked like female/or male small 1/4 wide spade connectors on each end, they were destroyed but used with the splice, this is the confusing part, having such big wire with so small connector, but this is found allot elsewhere in the system.
