It can not just 'find out' what you plugged into it and adapt to what it has, you have to have it connected properly - but without a schematic, or at least a board picture it is very hard to guess. Most likely it is designed to have all of them (or at least GND and one of the positive supply rails). Your panel has 3 wires going to it: the GND, +5V and +12V.

However, as you can see from the pictures that means actually connecting the negative supply lead of the load ('black wire' in this case) to +5V, and the positive supply lead to +12V. That trick would use the voltage difference between the 5V and 12V rail to get 7V.

The panel most likely does not work that way. The hackish 7V wiring you included is irrelevant in this case. In normal cases, this should not have posed a problem, as the power connector should have both ground sockets populated and connected together. (Be sure to double check which hole you put it in.) Pioneered by Molex Connector Company, the two-piece design became an. Now you have to bend the tabs so that when you put the pin back in, it will keep the pin in place. Molex connector is the vernacular term for a two-piece pin and socket interconnection. With a small screwdriver, you can gently bend them back to be level with the pin itself, and pull out the pin gently with the wire attached. If you look at the pins closely, you can see 2 small tabs bent out from the pin itself that keep the pin in place. One solution would be to move the ground pin on the fan controller cable to the proper position. Removing the wires without damaging the connectors is a simple method of enabling users to switch the polarity of actuator wires without needing to obtain additional Molex connectors or Molex housing.The ground pin is not connected. Once the header pins push back the hooks, Molex connector pin removal is simple, and the wire can slide out of the housing by pulling back on it without causing any damages to the power connector. This is completed by pushing the header pin into the thin gap between the metal power connector and the plastic on both sides of the housing. In this tutorial, we are using flat header pins that are used to release the hooks. Since there are two hooks keeping the connectors in place within the housing, they will need to be pushed back to release the wires. Part 3: Removing Wires with Crimped Power Connectors from a Housing However, there is a method of removing the wire from the housing without damaging the power connector. Once the crimped wire has been inserted into the housing, it will be difficult to remove. The power connectors have hooks that allow the connectors to latch into the connector housing. To disconnect a Molex connector (male and female connection), simple press down on outside clip and pull the connectors apart. Try crimping the wire again and inspect the crimp before inserting it into the housing. If the power connector pulls out or the wire comes loose, it means that your crimp was faulty. There are two housing options available, namely, a male housing (female power connectors) and a female housing (male power connectors).

For example, a Progressive Automations control box may require the actuator wires to have a designated orientation to obtain an extend and retract sequence that correlates to the ‘up’ or ‘down’ activation buttons on a wireless remote. The orientation of the wires can be based strictly off preference and will depend on the Molex wiring required for the type of system that you are working with. The crimped wires can now be fed into the connector housing. Part 2: Adding Wires with Crimped Power Connectors to the Connector Housing Clamp down on the crimping tool and release.Įnsure the correct power connector is crimped onto the wire depending on if you use Molex connectors that are male or female. With the stripped wire inserted into the un-crimped power connector, load it into the crimping tool.Īlternatively, insert the un-crimped power connector into the crimping tool without the wire, and then feed the wire into the connector (either way works). Therefore, the optimal length of exposed wire is 2.5 mm (the length of the crimp zone). The amount of exposed wire should not exceed the length of the power connectors insulation and crimp zone, which is 5mm. Part 1: Stripping the Wire and Adding the Power Connectorsīegin by using a wire stripping tool to strip back enough wire, ensuring proper connection when crimping on the power connectors.
