A multilayer, monolithic electrical interconnection device includes a substrate and a plurality of overlaying, alternating conducting and insulating layers deposited atop the substrate and one another. The layers are deposited by thermal spraying of respective insulating or conducting material through defined apertures in respective spray masks. Interlayer electrical connections are intrinsically formed by direct metallurgical bonding between the conducting material of an overlaying layer and the conducting material of a previously sprayed layer.

An automotive electrical system including a wiring harness incorporates the dedicated test line passing through critical connectors and components for allowing detection and isolation of improperly connected connectors. The dedicated test line can feed through expansion connectors, termination connectors, and junction blocks. Connector fault detection and isolation is achieved using time-domain reflectometry after final assembly, during vehicle servicing, or on-board during vehicle usage. A large number of expensive and inconvenient vehicle quits and tow-in's are avoided that would otherwise occur.

An automotive electrical system including a wiring harness incorporates a dedicated test line passing through critical connectors and components for allowing detection and isolation of improperly connected connectors. The dedicated test line can feed through expansion connectors, termination connectors, and junction blocks. Connector fault detection and isolation can be performed as a test after final assembly and during vehicle servicing. A large number of expensive and inconvenient vehicle quits and tow-in's are avoided that would otherwise occur.

An automotive electrical system including a wiring harness incorporates a dedicated test line passing through critical connectors and components for allowing detection and isolation of improperly connected connectors. The dedicated test line can feed through expansion connectors, termination connectors, and junction blocks. A respective impedance is connected between the dedicated test line and ground at each respective connector. Connector fault detection and isolation is achieved by measuring the total impedance presented at the beginning of the test line. The measured impedance uniquely identifies the locations of any improperly connected connectors.

A fuel injection control system coupled to a multiport fuel injected engine for adjusting the air/fuel mixture of each combustion chamber to a preselected level. A plurality of fuel command controllers provides a separate fuel command signal to each fuel injector in response to a single base fuel command. During each correction interval of a correction time period, each of the fuel command signals is perturbed or offset in a predetermined sequence by a predetermined amount. A measurement of the average of air/fuel ratios among the combustion chambers is taken each correction interval. Airflow inducted into the combustion chambers is also measured. In response to these measurements, and the known fuel offsets, the actual fuel delivered by each fuel injector is calculated. All the fuel command controllers are corrected in response to associated fuel calculations to balance the air/fuel ratios of each combustion chamber.
