Piggyback spade crimp terminals let you connect two wires to one 6.3 mm male tab. The female receptacle pushes onto the device tab, and a second 6.3 mm male tab on its back takes another female spade, such as our FDD1.25-250 female spade terminals. Pick the colour by wire size: red PBDD1.25-250 for 0.5-1.5 mm² wire, blue PBDD2-250 for 1.5-2.5 mm². To add a plug-apart joint in a single wire instead, use our MDD1.25-250 male spade terminals with the FDD.

Wiring & getting started
- Check the sizes with power off
The device tab must be 6.3 x 0.8 mm. Choose red for wire with a 0.5 to 1.5 mm² conductor and blue for 1.5 to 2.5 mm². Thinner wire in a blue terminal won't crimp tight, so use red for it.
- Strip and crimp
Use a crimping tool with the die colour that matches the sleeve. Strip to the length of the wire barrel without cutting strands, push the conductor fully in, then crimp the sleeve. Tug test the wire.
- Fit both connections
Push the receptacle fully onto the device tab; it should take a firm push. A terminal that slides on loosely will heat up, so replace it. Then push the second female spade onto the piggyback tab. Both wires now share the device tab, so add the two loads together and make sure that tab and its circuit can carry the total.
- Adjust and cover
The piggyback tab is angled to give the second terminal room. If it needs to clear a nearby part, bend it gently once, as repeated bending can crack it. The receptacle and tab are bare metal, so cover them if they could touch other conductors or be touched while powered.
