OPINION

Marcus Monteiro Albuquerque and Thomas Vincent Radice appeal from a judgment *278 convicting them of interstate transportation of a vehicle knowing it to be stolen, in violation of 18 U.S.C. § 2312 .

On December 17, 1974 defendants were stopped in Los Angeles, California, by police officers. The automobile in which defendants were riding had been reported stolen in Newark, New Jersey, on December 2, 1974 by the owner who had left the keys in the ignition. When stopped by arresting officers each defendant used an alias, and both admitted upon questioning that they drove the automobile from New Jersey to California. At the trial a police officer testified that both later admitted that they knew the car had been stolen.

When defendants were arrested, electrical bypass wires, electrical tape and a screwdriver were taken from the car. At trial, these items were offered into evidence and, over defendants’ objections, were admitted subject to a limiting instruction that they were received not as evidence of any guilt of defendants as to the theft, but for the sole purpose of determining their intent and knowledge.

To sustain a conviction of interstate transportation of a stolen vehicle the following must be proved beyond a reasonable doubt: (1) that the automobile was stolen; (2) that defendants transported the automobile in interstate commerce; (3) that defendants knew the vehicle to be stolen at the time of the transportation; and (4) that defendants intended to permanently or temporarily deprive the owner of ownership. United States v. Berlin, 472 F.2d 13 , 14 n. 2 (9th Cir. 1973); Lawrence v. United States, 400 F.2d 624 (9th Cir. 1968).

It is true, as appellants contend, that the items here in question were not probative of any of the above elements, and their admission thus improper.

“Hotwiring” tools may be relevant to show the capacity or means to steal an automobile, but, in the instant case, defendants were not charged with the theft of an automobile. Furthermore, although relevant to showing defendants’ capacity to commit a theft, the “hotwiring” tools are not relevant to establishing defendants’ capacity to transport. See, e. g., Moody v. United States, 376 F.2d 525 (9th Cir. 1967); United States v. Laker, 427 F.2d 189 (6th Cir. 1970).

And finally, the “hotwiring” tools are not relevant to show defendants’ knowledge that the automobile was in fact stolen, or that defendants intended to deprive the owner of the possession thereof. See United States v. Golembiewski, 437 F.2d 1212 (8th Cir.), cert. denied, 403 U.S. 932 , 91 S.Ct. 2260 , 29 L.Ed.2d 711 (1971).

However, even though the admission of the “hotwiring” tools was irrelevant to show any of the elements of the crime for which defendants were charged, their introduction was harmless beyond a reasonable doubt. Favors v. Eyman, 466 F.2d 1325 (9th Cir. 1972); Olivas v. State of Arizona Ex Rel. Eyman, 447 F.2d 974 (9th Cir. 1971); United States v. Porter, 441 F.2d 1204 (8th Cir. 1971).

The totality of the other evidence presented is clearly sufficient to sustain the jury’s decision, and the admission of the tools in question could not have had such an impact as to contribute to the defendants’ conviction.

Affirmed.
