Here is a segment of the Yamaha 701 instructions copy and pasted from the .pdf instructions. It does not explicitely mention a wire that is red with black tracer and regarding the connect each matching color to the existing OEM colors, I do not know of an OEM red with black wire in there, so something is strange.
However, if the two red wires with black stripes that you are talking about are soldered/crimped together with a waterproof bullet connector such that one available red/black is male and the other is female (and you are sure that this box is for a Yamaha 701) then I think they are the wires that go in series with an existing red connection.
Hope this helps.
Install the programmed Super Jet Ignition into the Electronics Module.
1. Re-attach all wires exception of matching colors. You will end up with a Red wire from the T3 Ignition and a Brown/White
in the electronics box.
2. Locate the Brown/White wire then cover the connector end with black electrical tape and set it aside.
3. Locate the Red wire from the T3 Ignition. The wire is fitted with both a male and female in-line connectors.
4. Find a red wire with in-line connectors close to the T3 ignition and separate this connector pair.
5. Connect the T3 Ignition Red male plug into the Red female socket in the electrical box.
6. Connect the T3 Ignition Red female socket into the Red male plug in the electrical box.
