On my 99 f4, the two front flush mount turn signals, have two wires just hanging there. I can't find ,where to plug them into. . Please help me find these wires coming from the bike. As soon as I get those wired, I'm putting bike back together and taking a ride. Thanks

This is the wires from turn signal, where do i put them ?

 

Hi and welcome! :wave: Did you just get this bike?

OEM turn-signals have 3-wires:

- ground
- running-light power
- winker-light power






Take off bodywork more so you can see all of factory wiring harness. Original turn-signal connectors are blue and orange and may be taped up against harness. They look like this, but are 3-wire versions:




DO NOT hack up harness connectors to connect those turn-signals!!! You'll cause more problems that'll take years and thousands of $$$ to fix! Continuously blowing fuses and not-starting. Hyper-flashing, rear-signals not working, etc.


1. Instead, chop off flushmount's bullet connectors and attach to mating connectors with 2 diodes so they are plug & play into factory harness: https://www.corsa-technic.com/catego...ategory_id=278

or

2. get adapters, but you'll need to find 3-way adapters with 2-diodes so running-lights AND turn-signals will work: https://www.ebay.com/itm/173004358611

or

3. if factory 3-way connectors have been hacked off. Restore them to OEM condition with 3-way female connectors. Then add 3-way male connectors with 2-diodes to flush-mount signals so both running-light and winker-lights work properly. https://www.corsa-technic.com/catego...ategory_id=278




Really, you'd be better off putting back on OEM turn signals with matching 3-wire connectors so you can just plug them straight into harness. And they'd work right away. Running-lights will stay ON full-time for safety. And lights would blink on & off for turn-signals for safety. Don't risk your life to look "cool" with flushmounts!!!

 

i installed flush mounts on the front of my 99 knowing they were only 2 wire. i am curious about the diode (do you mean resistor) modification so running lights and turn signals work. do you have a write up on that?

 

Ballast resistors for LED lights are stupid, just get proper solid-state flasher relay. Not resistors, DIODES.

Diode provides one-way current-flow to create an OR circuit. So when either running/marker line has power OR winker circuit has power, then bulb will light. Wire them up like this to connect 2-wire winker-lights to 3-wire Honda harness. Diodes isolates 2 power-circuits to prevent back-flow of power to other circuit and prevents running/marker lights from lighting up turn-signal indicator on dash. Be sure to measure harness-connector to determine which terminal is ground, running/maker-light and winker-light.

The F4 actually uses a combination of connectors for the turn signals. It uses a 2 pin similar to what is indicated above, and then uses a Bullet connector for the ground wire, which is Green in color.

 

Cool thanks!

So green ground bullet connects straight to black ground on lights.
You can just get these adapters then. Snip them and insert 2 Diodes with stripe aimed towards lights, join outputs to one wire, solder, heat-shrink and you're done!
