I have a 94 impreza and I just bought a different down pipe for it it came with a lambda already in it with a square connector and three wires however the one on my car at the moment has two wires and a round connector I can't swap the lambdas as they are different sizes and won't fit any help please guys

Can you take a pic ?

Easiest thing to do would be take the new one to a fabricators get them to weld you a new bung on take the old one out and weld that up unless it's for an afr gauge

It'll have to be tomorrow now ive managed to find a two wire lambda now too so will fit that and should be all good if not I'll post again. Thanks for reply tho.
