These AiM adapter cables have a female 4-pin 719 connector at one end and a male 4-pin 712 connector at the other to connect most analog automotive sensors to the MyChron3 XG-Log Auto Dash or AiM EVO4 Data Logger. Available in 0.5 thru 4 Meter lengths. The MXL and MyChron3 Auto Dashes (except the XG-Log) use a different 719-719 Patch Cable (Part No. MC-211) to connect sensors with the 719 (4 pin plastic push-on type) connector to the dash harnesses.
