Title: 75 2.0L TS - Motronic Wiring Question
Post by: Tristan Atkins on May 01, 2009, 01:00:50 PM
Hi Guys,

Would anyone know what I should connect, to the following wires?

The car had the usual "professional alarm" installed  - aka scotch locks and hard wiring to the battery. I thought it better to return it to the origional set-up.

Cheers,

Tristan

Pink wire should be power feed to the fuel pump, black wires should be earth.  The other two I'm not 100% on off the top of my head but on most Jetronics and earlier motronics, one is normally supposed to be live power and the other ignition power.  Should be no issue with hooking both up to ign power though.  A quick search on the net will most likely reveal the answer to this one for sure.

I'd be making sure that firewall is waterproofed though, looks like a nice bit of tin worm developing underneath the ecu...

There's a guy "Craig" on Alfa BB who is a wealth of knowledge of Alfa 75's. Has a free owners manual section. Follow him up i'm sure he will reply . He's actually a Melboune boy, but unfortunately post much on this site.

Cheers

Hi Gully and Jekyll & Hyde,

Thanks for your comments. I have already spoken with Craig on the Alfa BB and he provided me with a pic of the earlier (non cat) loom. Unfortunately the layout is different along with the colours of the wiring so I'm still stuck.

It's actually a conversion into a 116, but I was hoping that some of the 105 guys with TS's might know?

Also, Jekyll &Hyde do you know anywhere to look online for the standard colour practice for Alfa Romeo's?

Cheers,

Tristan
