General No power to diagnostic plugs

[wiley17]

As per my previous post-an independant tried to plug in a diagnostic machine to the two plugs located on the fuse box in the engine bay but the diagnostic did not power up.His obvious conclusion is that there is no power to these plugs therefore we cannot diannose the ABS fault.Anyone got any ideas as to why both these plugs would be dead?Help much appreciated

there shouldnt be any power on a 3pin fiat plug

to connect an obdII reader to a fiat 3pin plug you need 4 lengths of wire. use 3 lengths of wire to connect the 3 pin connector to the obd connector. also use 1 length of wire for power to the obd connector.

on the 16 pin obd2 connector use the following pins
4- chassis ground (connect to ground on 3 pin connector, or any good chassis earth)
5- signal ground (connect to black wire pin on 3 pin connector)
7- k line (connect to white wire pin on 3 pin connector)
16- 12vDC (connect to battery positive terminal)
